Department of Defense Small Business Contract Essay

Department of Defense Small Business Contract - Essay Example (2009). Advantages 1. The requirement for this contract is only the delivery of the agreed merchandise, for which the contract was agreed. 2. Can also be used to test unknown contractors 3. It provides for a situation in which there is competitive bidding on the entire scope 4. Management by the owner is least required 5. It provides an incentive for the contractor to equip best resources Disadvantages 1) It bears a heavy risk to the contractor as s/he assumes the cost risk 2) Both the schedule and quality of risk is heightened 3) A very complete and in-depth definition will be needed upfront 4) There will be more costs attached when changes occur than in cost-reimbursement 5) The total schedule of the bidding process is lengthened in this case Cost-reimbursement contract This is that contract whereby a given contractor is compensated for every of its acceptable costs or rather expenses to a given limit, plus an additional imbursement to thrive to some profit (Project Management Inst itute. (1987). It is a contract with a fixed price contract, whereby the contractor is issued with a negotiated sum f money irrespective of the expenses that may be incurred thereof. There are various contracts namely the time and materials contract, the cost-reimbursement and the fixed price contracts. Each contract comes with its own performance risk and/or cost for the various agencies especially the governments but the different kinds of the cost-reimbursement contracts could be employed be it in form of the award fees, incentives etc that are put in place to motivate the contractor and subsequently dispel waste and inefficiency by the given contactor (Heldman, et al, 2007). Cost-reimbursement contract pay s the said contractor’s acceptable costs that are incurred to such extent set by the contract but may also pay an additional fee related to the performance. Such contracts do include an estimated sum intended to obligate the funds and a ceiling to that said contractor w hich exceeds at its own risk, unless agreed on and approved by the contracting personnel. This type of contract may be used in situations in which the accounting system used by the contractor for determination of costs is easily applicable to the contract and where appropriate surveillance at the time that the performance is underway (Schwalbe, K. (2009). Advantages 1) It’s also used in a situation where there is a concern in the long term quality is quite high. 2) In this case, final cost might be lower than some fixed price contract due to the fact that the contractors never inflate their prices to cover risk. 3) It has some small incentive to negotiate corners as opposed to the fixed-price contracting (Project Management Institute. (1987). Disadvantages 1. Oversight and administration is also needed in the designation of an award to be offered or any such appropriate incentive. 2. Additional administration and oversight is needed to ensure that it’s only the permiss ible costs are paid and that adequate general controls to costs are instituted. 3. Certainty is limited to the exact final cost (Project Management Institute. (1987). 4. The incentive provided to be efficient in itself is smaller as compared to the fixed-price contract. Advantage of the small over big companies in contracting There are a number of mechanisms that the government has set

PEST(LE) Analysis Essay Example | Topics and Well Written Essays - 1500 words - 1

PEST(LE) Analysis - Essay Example In UK market, there is further scope of growth for the company. UK’s consumer market demand is well aligned with business strategies of IKEA. The company has been able to secure desirable market share due to its effective cost control strategies, continuous new product development and competitive operational procedure. IKEA is inclined towards offering low prices to customers for its wide array of innovative products. According to Allen (2006), PESTEL analysis is a strategic tool that helps to determine key drivers of change present in the business environment. The main components of this tool are political, economic, social, technological, environmental and legal factors. Political factors stands for government policy which directly impacts workplace environment, technology quality, health and safety conditions, etc. Economic conditions include interest rates, rate of economic growth and taxation charges. Social factors relate to all possible events which are affecting community and market socially (Allen, 2006). As per Das and Teng (2009), it comprises of population dynamics, cultural expectations, norms, health consciousness, etc. Technology factor states that new products or processes are developed with the support of advanced technology. This factor facilitates quality enhancement, innovation and reduction in overall costs. Legal aspect corresponds to legislative and regulatory framework tha t governs countries of operations or respective product areas. Environmental factors encompass changes in climate and weather. Environmental awareness is an area of concern for all business organizations (Das and Teng, 2009). Research methodology lays the foundation for any research study. Any study can be classified as quantitative or qualitative research study. Quantitative study deals with market related data which can be statistically analyzed. On the other hand, qualitative study is opinions or views of experts. There are two

Todays Society Vs Ideal Society Sociology Essay

Todays Society Vs Ideal Society Sociology Essay In The Communist Manifesto, the authors Karl Marx and Engels feels that this capitalism with the help of industrialization is the increasing the productivity of economy way beyond expected. This is the main reason for class struggle where the oppressor rule and ruin the oppressed class. In short Capitalism has turned out to be a money making system in which rich people own private properties and to stay in the market, they distribute it according to the growing competition amongst themselves. Capital is therefore not personal, it is social, power(Marx and Engels 24). On the other, Thomas Mores Utopia is completely a different society called as an ideal society where people do not run their business for sake of profit but still live a peaceful life. The reason for peaceful and happiness in their life is unity and public ownership which solves the main social problems such as poverty and inequality. The political laws, religious principles and social issues are development in such a ma nner that it benefits not a single individual but the complete utopian society. Not only throughout the history but also in todays society money is consider as a key to success and people think that power and fame along with the rise our their wealth. In the Communist Manifesto, the authors Marx and Engels point out that rise of capital as the main source of class struggle. Society as a whole is more and more splitting up into two great hostile camps, into two great classes directly facing each other Bourgeoisie and Proletariat (Marx and Engels 9). The Proletariats are the low working class society that live on the labor power and do not make any profit but rather work under Bourgeoisie to produce goods for the society. On the other hand Bourgeoisies are upper class people that own private properties and business that make profit by exploiting the Proletariats. A business can only make profit when the income of capital is more than the outcome or the expense. This is possible by making the labor class, work more and pay them less. The average price of wage-labor is the minimum wage, i.e., that quantum of the means of subsistence which is absolutely requisite to keep the labor in bare existence as a laborer (Marx and Engels 24). T his leaves labor with no choice, but to work under the upper class for their daily living. The authors believe that this upper class people should focus more on the improvement of their labors living, as they are their sole mode to earn profit. The class struggle has still not ended, in fact the rich are becoming richer and poor becoming poorer and wealth is the one responsible for this status. The case in Thomas Mores Utopia is different. He has made up a destination named Utopia which is known for the ideal society, a perfect and a social life where there is no competition among the people. This is complete different society which has different principles which treats everyone equally and more importantly, no one owns any property by himself. Agriculture is the main occupation and each family is given a piece of land. One of the principles that is different from todays time is that Utopian family has head of household that takes the things needed without any exchange for money or direct goods. Certainly fear of want makes all kind of animal greedy and rapacious, but only mankind is made so by pride, which makes them consider their own glory enhanced if they excel others in displaying superfluous possession, and in Utopia there is no place for such thinking. If everyone begins to think in such a manner, than there are chances that we could gain freedom from class struggle and achieve unity. The Utopian laws are very fair to people because every decision is taken for the benefits of the complete society. However, some of these laws are illogical and hard on people. For example, the son must have same trade as his father. But if anyone is drawn to another occupation, he is transferred by adoption into another household where he can work at the trade he wants to pursue. This breaks the bond a child has with his family just to achieve different trade. However, after mastering both the trades, he gets to practice whichever he wants until and unless there is higher demand of the other trade in the city. Moreover, he works for the trade which benefits the society as a whole and not himself as an individual. The education in Utopian society is not mandatory and very few people are allowed to leave their labor work for education. They also believe that value of life is gained through education for which every child is given complete education. It is interesting to find that alth ough the Utopians have labor work as their main career; most of this people are seen doing intellectual studies in their free time. In todays time, the education system is in danger and needs to be rescued from the influence of the ruling class (***). This upper people, with the influence of Modern Industry, are affecting the education of children of working labor class. This leads to transformation of their children to simple articles of commerce and instruments of labor (***). Nowadays there are some countries which has public schools providing free education to children. Utopia is titled as communist state not only by critics but also by the authors of The Communist Manifesto, Marx and Engels. After reading the text, we find Utopia as communist state. It is mentioned in the Manifesto that profit and competition is damaging the importance of the community: The bourgeoisie, wherever it has got the upper hand, has put an end to all feudal à ¢Ã¢â€š ¬Ã‚ ¦ has left no other bond between man and man than naked self interest, than callous cash paymentà ¢Ã¢â€š ¬Ã‚ ¦ has resolved personal worth into exchange value à ¢Ã¢â€š ¬Ã‚ ¦ and has set up that single, unconscionable freedom Free Trade (11). Similarly, in Utopia, Hythloday quotes that wherever there is property, everything is in the terms of wealth and profit. He further tells that it is hard for the common people to gain justice until justice is served when all the best thing go to the worst people or that happiness is possible when everything shared among themselves who are not entirely happy, while the rest are plunged into misery (46). However, some communist nations share few differences with Utopia in terms of religion. We know that religion exist in Utopia and has similar believe like other religions i.e., there is only one God but might have different nature. Whereas the communist nations like China and Russia are among the top atheist country where 59% and 22% of the population respectively, doesnt believe in God and follow no religion (Atheist). We know also that in Utopia people do not own any money or property whereas in China official misuse power of their position to gain wealth for personal benefit. The text by Thomas More, Karl Marx and Fredrick Engels shows that there could be two possible societies, an ideal society, i.e., Utopian Society, where everything works with perfection and money has no value and the other society would be our present society, which is divided into upper class and working class based on wealth. People are considering money as the sole source of happiness. This thinking of ours is ruining many lives each year. Although the unfair treatment such as inequality, labor wage, and class struggle had started off in the beginning of Capitalism, still continuing and seems to be an endless one. Todays society detracts the attraction of being youthful by forcing work onto people in order to succeed. It is unjust to the workers who contribute the most to the society and receive very less in return. We must put an end to private ownership and encourage public ownership. In public ownership people dont own anything and poverty doesnt exist. However, people have a gu arantees life of happiness and stability.

Law School Admissions Essay - The Spirit Lives -- Sample Law School Ad

"Hasta la victoria siempre." (Che Guevara) I want to study law so I can help people with problems in the workplace.   I am unhappy with the decrease in real wages, the huge increase in temporary and part-time employment that includes few or no fringe-benefits, and the continued existence of unsafe work places.   I believe that technological advances are going to continue to put people out of work, perhaps on a massive scale, in the next twenty to fifty years, and that government, business, and workers will have a new opportunity to share the gains in productivity that are to come.   I believe that people have the right to work at a job that allows them to afford to raise a family, live in a comfortable, safe home, and work in a safe environment.   I want to devote my work to improving workers' pay levels, assuring them access to health care, paid vacation time, fair treatment by their employers, and physical safety in the work place.   Increasing the number of safe, well-paid, secure jobs will go a long way towards helping alleviate many of the social ills that are associated with poverty.   Ã‚  Ã‚   I was involved with labor issues at my job at the San Francisco International Youth Hostel, where I worked from 1992 to 1996.   I helped organize a group of workers there to discuss our work place and to smooth out scheduling conflicts between management and our group of workers.   In September 1995, part-time staff's holiday pay was taken away without any discussion at all, and I called the Executive Director of the Company the (The Golden Gate Council) and persuaded her to re-institute it.   I was regularly consulted for my opinion on various wage, hour and working-condition matters.   Ã‚  Ã‚   I have seen how working people organize them... ...ing as a community organizer for a volunteer service-exchange program that benefits seniors and the disabled.   the work I am doing reinforces the goals I have of helping solve problems in the workplace.   At my job here in West and South Berkeley, I have again seen the poverty that a dearth of good jobs breeds in a community.   I want to help raise my community's living standards through a more equitable sharing of the resources we transform in our workplaces.   Ã‚  Ã‚   The last thing I can say about myself is that I am interested in almost everything and hope to learn much more about solutions to social problems, science, questions of spirituality and religion, history, visual arts, music, literature, and the list could go on for a while form there.   The curiosity and interest in knowing about the world is an asset that I will take into whatever endeavor I choose.

Spontaneous Generation and Cell Theory

Spontaneous Generation and Cell Theory 1. Tradition thought is very hard to overcome- even with solid evidence to support new ideas * Social pressure has effect on acceptance of scientific ideas and technological advancements * Science is a social/political enterprise * New ideas often met with resistance * Sometimes ostracisms, persecution, death * Microscope helped to overturn some strange ideas * Disease processes * â€Å"spontaneous generation† Attitudes and skills of scientific inquiry (questioning, predicting, observing and recording) are required to provide unbiased and factual info * Investigations must follow ethical guidelines and results must be reproducible under controlled conditions * Example of way that science, technology and society are linked is found in development of the current understanding of the way living cells function * Microscope provided technology to explore the world of microscopic particles and organisms * Then possible to obtain evidence for or against generally accepted opinions or theories about living thingsSpontaneous Generation 2. Believed that life can emerge from non-living matter 3. A superstition- people unaware of microscopic forms of life * e. g. mice created from mixing wheat husks with sweaty undergarments * Maggots and flies emerge spontaneously from raw meat * Francesco Redi * Example of scientific method * Believed flies laid eggs on meat * Experiment to prove hypothesis Limited access to meat (air, no fresh air, flies, no flies) 4. Idea that life could emerge spontaneously from non-living matter = widely accepted from time of the Romans through to the 19th century * Even in time of Robert Hooke and Antoni van Leeuwenhoek * Believed that to produce mice, you put a sweaty underwear and husks of wheat in an open jar and after 21 days, the sweat and husks would combine and change the husks into mice 5. 668, Francesco Redi (Italian physician and poet) questioned belief that maggots appeared from raw meat * He believed that flies laid their eggs in the meat * Set up experiment to test his hypothesis * Set out flasks containing raw meat but some were sealed, some were covered in gauze and some were open to the air * Controlled the access of flies to the meat * Maggots were found only in the flasks that were open and accessible to flies to lay their eggs * Despite evidence, idea of spontaneous generation still thrived 6.John Needham (proving that living things could be produced from non-living matter) boiled chicken broth and put it in a flask and sealed it * Everyone accepted that boiling killed micro-organisms since boiling was a common method of removing substances that would make one ill * However, in his experiment, micro-organisms continued to appear * Suggested that there was a life force that produced spontaneous generation 7.Lazzaro Spallanzani (Italian priest) claimed that there were micro-organisms in the air that were responsible for the new growth * Re-did Needham's experiment but drew off the air in the flask, nothing grew in the remaining broth * Critics suggested that all Spallanzani had shown was that air was required for spontaneous generation to occur * Spontaneous generation theory continued to be accepted 8. 859, French Academy of Sciences announced a contest for the best experiment to prove or disprove spontaneous generation * Louis Pasteur used the work of Needham and Spallanzani with important change * Before boiling meat broth in flask, Pasteur heated the neck of the flask and bent it into an â€Å"S† shape * Air could reach the broth but micro-organisms and other particles would get caught in the S- bend * Nothing grew in this broth but if the flask were tipped so that the broth reached the S-bend in the neck, moulds would later appear 9.Pasteur controlled his experiment in that he used the same broth, same type of flasks and same light and temperature conditions * Controlled variables (conditions that are held constant throughout an e xperiment): broth type, flasks type, light, temperature * Manipulated ariable (condition deliberately changed in an experiment): access of dust to the flask * Responding variable (condition that changes in response to the manipulated variable in an experiment): ability to grow mould in the broth * Had experimental control, a part of the experiment which the manipulated variable is not changed in any way from its normal condition * Flask in which dust had normal access to the broth after boiling * Result: moulds occurred * Experiment treatment Prevent the access of dust to the broth, resulting in evidence of no growth of mould * To allow access of dust to the broth very briefly, resulting in evidence of mould growth * Strong evidence that says that spontaneous generation doesn't occur, but also that micro-organisms are found in the air * His work opened new doors to microbiology, immunology, biochemistry and gave credibility and new importance to the processes of conducting controlle d experiments, maintaining detailed records of observations, and connecting results to conclusionsThe Cell Theory 10. Importance of cell as the functional unit of life was recognized with the improvements in lens technology and increased number of observations made by scientists in several countries 11. 1833, Robert Brown identified an important cell structure, the nucleus, in study of orchids * Saw an opaque granular spot within the cell * Others had seen it too but he was the first to recognize at this cell structure must have something for cell function 12. 1838, M. J.Schleiden observed that all plants were composed of cells and he proposed that the nucleus was the structure responsible for the development of the remainder of the cell * Discussed his work with a friend (Theodor Schwann), who was studying animal physiology * Schwann believed that there must be similarities btwn plant and animal tissue * When Schwann searched for opaque spots in animal tissue, he found structures t hat resembled the cells that botanists were studying in plant tissue and the nucleus structure that Brown and Schleiden had identified 13. 839, Schleiden and Schwann proposed the cell theory as a result of observations of plant and animal specimens through the microscopes * All plants and animals were composed of cells and that the cell was the basic unit of all organisms 14. 1859, cell theory was further extended by Rudolf Virchow's statement that all cells arise only from pre-existing cells Cell Theory 15. All living things are made up of one of more cells and the materials produced by these cells 16. All life functions take place in cells, making them the smallest unit of life 17.All cells are produced from pre-existing cells through the process of cell division 18. Applies to all living things regardless of size, shape or number of cells involved * Subcellular particles (viruses and prions) fall into category that is neither living nor non-living although they may exhibit certai n characteristics of living cells 19. Evidence in support of cell theory came from Pasteur's experiment to investigate the concept of spontaneous generation in micro-organisms * Cell theory has become the cornerstone of the study of biology

Book of job: the unwritten message

The Bible is a library of many passages, written by authors from the ancient times dealing with different topics like creation, faith, suffering, glory. These and many more are scribbled all through out the texts and are divided into clusters called the books. The authors of these books came from different times and places. There are even views that additional chapters are added after the original book has been finished. Having said these, one cannot be sure of the exact origin of the stories, nor the message conveyed with in them. One of these books tackled on the idea of just punishment, a very simple one yet with a lot of twists. It was a part of the bible that was read, reread, and tested from time to time. Scholars tried to translate the many double meanings found in the book, as well as come up with their own ideas regarding it. The Book of Job tells the story of a man, Job, who had everything that he could possibly dream of. He has a nice family, good health, material possessions, and a peaceful life; all of which he thanked God for. This was noticed by the devil, who in turn made a wager with God – saying that Job only praises God because he has everything he would ever need, and that in times of misfortune he would definitely curse God. God agreed, and allowed Job to lose his possessions, his sons and daughters killed, his skin covered with boils, and his life completely ruined, provided that Job would not be dead. After these tragedies, the book focused next on the debates Job had with his three friends – Eliphaz, Bildad and Zophar. These debates marked the first of several conversations found in the book. The speeches were designed in such a way that Job answered each one of them and tried to defend himself. In the end, God himself talked to Job, taking part in another speech portion which led to God’s answers. The story ended with God giving back Job his lost health and wealth. God also ordered Job’s friends, who misinterpreted Job’s misfortunes, to ask him to pray for them. The Book of Job is a very controversial part of the Bible, since it deconstructs the logical belief on punishment – that a just punishment is given to those who have sinned and the level of the punishment depends on how grave the committed sin is. But for punishment to be rendered to someone like Job who in his whole life praised and worshipped God for all the goodness He has given him and the prosperity he has acquired, surely, we may say that there is injustice. That is why there are many assumptions on why God allowed these to happen to Job. It may be to prove to the devil that Job is really God’s man, or to show that God is really all powerful and all righteous, or it may also be for the atonement of the sins that Job’s sons had committed. These are wild guesses and can’t be really answered without reading and understanding the book as a whole. In the story, God responded to Job’s questions by a series of statements that could mean many things. His replies are intellectual, and may be interpreted in many ways and may take many points of view. In fact, the story itself may be seen in many ways. It all depends on who reads the text and how the said text is understood. The last chapters of the book define many things and answer a lot of questions that is reflected all throughout the book as well. To narrow it down, God’s reply can be found in chapters 38 to 41. The first verses from the said chapters may be analyzed in two ways. At a first glance, one can see God’s answers to Job’s questions as proof of His omnipotence and self righteousness. And the questions such as ‘Where were you when I laid the foundations of the earth?’ (Job 38:4), ‘Have you seen the gates of death?’ (Job 38:17) and ‘Who provided food for the young?’ (Job 38:41) that seem to have God as the only answer thus proves His confirmation of   His omnipotence and self righteousness more. They can be interpreted as God’s way of proving to Job that though the reasons behind His actions may be uncertain to us humans, He, in contrast, as an almighty being is certain of them. Another possible explanation would be that of God’s attempt in providing proof that ideas such as that of providence and purpose exist; purpose defined as being the reason given to everything that happens within the realm of God and providence as His way for intervention with everyday human life. And so, these assumptions suggest that there indeed is a purpose behind Job’s suffering. This â€Å"purpose† is also evident in evil which can be seen in God’s second speech to Job. God portrayed evil in the form of two fearsome beasts – the behemoth and the leviathan. The behemoth was described as having â€Å"bones of brass and gristles of iron† (Job 40:18). And that it could be found in the mountains eating â€Å"ox as if they were grass† (Job 40:15). On the other hand, the leviathan was depicted as a beast that lives by the river and that it has skin so hard it would be questionable to â€Å"pierce it with barbed irons and fish spears† (Job 40:31). The Bible had even more descriptions of this leviathan scattered in the Book of Isaiah, all pertaining to the beast as a possible manifestation of evil itself. Having said these, God made a point to Job that humans are indeed no match to these beasts and that nothing could bring them down except God Himself. In doing so, He admitted to have created these evils and He alone has the power to banish them (Job 40:19). Therefore, God concluded in His second speech that the purpose of evil in this case, Job’s suffering, will be explained at the end of the world as He smites the beasts. God, in His conclusion, only gave a hint of His side of the argument without actually producing a clear answer to Jobs many questions about his misfortunes. In this lack of explanation, a chance opened up for Job to question and criticize God. But instead, he still chose not to condemn God but to worship Him even further. It seems that despite everything, he understood the existence of the hidden purpose in evil. He also came to realize that had judged God prematurely and without faith. By analyzing God’s response to Job, we can draw a number of conclusions as to what He wishes us to understand. One is the purpose in evil, which was discussed in the previous paragraphs. Another is the presumptuousness of mankind. God may want to show that humans think that they know all. But by asking questions such as ‘Do you observe the calving of deer? Can you hunt the prey for the lions?’ (Job 39:1), He can easily mock this said high intelligence of humans probably hoping that instances as such may instill humility. Also, in the debate between Job and his friends, we can see another pitfall in human perspective, which is the hasty judgment of suffering as the end result of wrongdoing. It was stated in the book that his friends even asked Job to repent for sins that he didn’t commit. This is because we tend to see a misfortune merely as a retribution for offense. In line with this thinking, we automatically assume that there is a need for repentance, and that it is the only way to redeem ourselves and be given back what we lost through misconduct. The next conclusion is the mentioned existence of the end of time where unanswerable questions will be answered. It is also in this said time that God will put an end to the evil He has created. Finally, the statements made by God reveals a kind of test for us humanity – Will we condemn God so that we can justify ourselves? The Book of Job may seem controversial, but God in the end provided some sort of answers which to some may be incomplete. The way to view this book may differ from time to time, from reader to reader and from place to place. We really can’t put our finger on what the final message is but I believe that the conclusions drawn above are enough for now.   Summarizing the whole paper, we humans seem to have a certain fear against punishment, and quickly tie it with some sin or some failures. The Book of Job awakens us that the reasons for punishment come in different forms, and as long as we are certain of our faith, we must not judge and condemn anyone, for that matter, prematurely.

Seepage Tank Lab Report Essays

Seepage Tank Lab Report Essays Seepage Tank Lab Report Paper Seepage Tank Lab Report Paper Measure the water level (head) difference. 2. Once the flow reaches its steady state (i. E. When a constant outflow rate is maintained), record the elevation head (by reference to an arbitrary datum such as the base of the tank) and the pressure head at each viscometer. Also measure the water and sand levels (relative to your datum), and the dimensions (length, depth and width) of the tank. 3. By injecting a small dose of dye just below the surface of the sand (against the glass) on the upstream side, trace the path Of the flow line by marking its movement with time on the glass. . Observe the change in velocity of the flow as it travels from the upstream sand surface to the downstream sand surface. Explain Why the velocity increases as the flow gets closer to the barrier wall and reduces as it moves away from the wall. 5. Repeat the above to trace a few more flow lines with an aim to provide enough information to assist you to sketch a flow net. Comment: LAMI NAR FLOW note the flow through the sand is laminar as the path traced by each shot of dye is a streamline flow and is not dispersed as in a turbulent situation. Confirm this by putting a shot to dye into the sand but this time away room the glass. The dye will reappear at a mirror position on the other side of the barrier wall. Also note that the now from the sand surface to the outlet on the right side is also a streamlined flow. 6. Measure the outflow rate by using a beaker and a measuring cylinder, Convert this flow rate to litter per second per meter width of the tank. 7. With the preceding flow line information, sketch a flow net (to scale) to represent the seepage flow in the sand. . From the flow net, calculate the discharge (per meter Width Of the flow net model). The k value of the sand can be estimated from the Hazes Equation low: k = 100 0210 where k is in units offs/sec, and DISC in units of CM (DID of the sand is posted near the model) 9. Compare this calculated discharge with the flow rate measured in (6). Suggest reasons for the difference (if any), 10, Based on the flow net, calculate the total head at each viscometer, Compar e each calculated value with the one measured in (2). A small dose of dye is injected just below the surface of the sand on the upstream side and the path of the flow line is traced by marking its movement with time on the glass. The final result when all the dye emerges at the downstream side is shown in Figure 1. Figure I : Traced glow Lines 4. The flow velocity increases as the flow gets closer to the barrier wall and educes as it moves away from the wall. This is because as the flow rate is constant (Conservation of mass) while the area of the flow cross section decreases when it gets closer to the barrier wall, the flow velocity increases. This is best understood by referring to the continuity equation, Alternatively, it can also be explained by referring to the equation , where the k value is constant while the hydraulic gradient i defined by AL/L increases because the head difference is constant while the flow length L becomes shorter when it gets closer to the barrier wall. 5. The final result when all the dye emerges at the downstream side is shown in Figure I _ 6. The outflow rate is measured by using a measuring cylinder _ It is measured 3 times and averaged for a more accurate result. The results are shown in Table 2. Measurement Average Flow rate (l,sec) 4. 17 Table 2 : Flow rate measurement The result is converted to mm/sec per unit width as shown below 7. With the preceding flow net information, a flow net is sketched and presented in Figure 3 of the attached Appendix 1. 8. From the flow net in Figure 3, the flow rate is calculated as shown below.
