Heat Engine Lab Essay Example

Heat Engine Lab Essay Example Heat Engine Lab Paper Heat Engine Lab Paper Heat engine lab Intro: when an engine runs, it pumps pistons that move up and down and provide energy to the engine to it to go. These pistons move because of pressure and heat. This work done on the system is not only mechanical but its also thermodynamic. When a piston undergoes one full cycle its displacement is zero because it comes back to its resting place. This means that its net thermodynamic work to be done should also be zero, as well as its total internal energy. In order to test this experiment is setup with the purpose of verifying that the mechanical work done in ifting a mass, m, through a vertical distance, h, is equal to the net thermal dynamic work done during a cycle by a mass lifting the heat engine. If we calculate the values for thermodynamic work and mechanical work they should be the same. Once these values are calculated they will be compared to each other and the conclusion will be drawn. Analysis: Once the results were printed, some values had to be calculated and compared to one another. The first value needed was the Thermodynamic Work on the system hich was founded by the equation: With=(pi(dA2))/4*(Pb-Pa)*(hc-hb). Where d was given to be 32. 5mm, Pb and Pa where the pressures at the points B and A measured in kPA, and hb and hc are the heights of the piston at point B and C. This comes out to be: Wth= 1. 37EA-2J. Next, the mechanical work had to be calculated using the equation: Wm= mgh. Where m is the mass in kg, g is the acceleration due to gravity, and h is the change in height from B to C. This comes out to be: Wm= 1. 47EA-2J. When compared together these values should be identical because a Joule is a Joule s a Joule and the values shouldnt change. These reigns true with this experiment because of how close these values truly are to each other. Questions: 1). The temperatures do change from B to C and from D to A 2). Yes there is thermodynamic work done from B to C which is positive, and from D to A which is negative. 3). Internal energy of the system has no change because it came back to its starting place; this also is true for the net thermodynamic work done. Conclusion: In conclusion our experiment was a success. Once the experiment was run and the esults were printed, the values for thermodynamic work and mechanical work were calculated using the previous mentioned equation. When these values were composed to each other they were extremely close in value. These numbers were supposed to be identical thus its impossible to calculated the percent error because you can divide by zero. All though the percent error cant be calculated these were still extremely close to each other which shows that the experiment was a success and the purpose was proven right. heat engine lab By nlarocco

Organization and Environmental Analysis Essay Example for Free

Organization and Environmental Analysis Essay Huawei Technologies technical diversification of its portfolio and value addition to its existing products is highlighted by Huawei being ranked amongst the top 5 in the world in terms of essential UMTS patents. By June 2008, Huawei had filed 30,569 patent applications. (Huawei Corporate Information-Huawei Media release). The big inclination towards RD and strong cost differentiation has enabled Huawei Technologies to achieve what the other dominant players in the telecom industry have been struggling to achieve- customization! .This strong customer focus is also the face of Huawei Technologies projected through its brand logo. The Huawei Technologies brand logo reflects its core principles of â€Å"customer-focus, innovation, steady and sustainable growth, and harmony, conveying Huawei Technologies sincere commitment to helping its customers realizing their potential to launch a variety of competitive services through continuous innovation and an enterprising spirit. † (Huawei Corporate Information-Huawei Media release). The Huawei Technologies logo was recently changed and modified to reflect harmony as also one of its key elements, so as to convey its social responsibility. Huawei Corporate Information-Huawei Media release). This has brought in the much needed image change required by Huawei Technologies primarily being seen as a Chinese vendor. Figure1: Huawei Contract Sales (Source Huawei Corporate Information-Huawei Media release) Opex Capex leverage which Huawei Technologies has been able to offer its customers has enabled it to demonstrate cost leadership which is evident as 72% of its contr act sales were from overseas market in 2007. Let alone in 2007, it had 45% increases in its contract sales revenue. See figure 1. Huawei Corporate Information-Huawei Media release). The strong hold which Huawei Technologies is being able to maintain also comes from the socio-political environment it works in as the labour cost in China is one sixth of that of United States or Europe. Thus it has become a key external environmental factor . Internally Huawei Technologies has capitalized on human resource and RD. But has the cost differentiation been enough, will it still promise growth and more market share? These are the biggest questions which need to be addressed for a guaranteed continuous growth. This question has made Huawei Technologies rethink its marketing strategy towards value proposition, and to value chain analysis (Porter 1985) for a bigger market share. Before that however lies another hurdle of poor quality perception a question mark on the quality of Chinese branding. Issue 2- The dragon brand wagon. With the FMCG market taking blows after blows because of adulterated Chinese raw materials, the general consumer perception on Chinese quality is struggling to establish a stand. Though it specifically affects as said the FMCG market or the business dealing in B2C but the general perception affects all including B2B. And this has been one of the prime challenges. From 1998 to 2001 Huawei was looked at with distrust doubt . With the Cisco lawsuit the market penetration in the developed economies had become more difficult and required 1000 times more effort as compared to its American or European counterparts. (The Economist, Nov 2007). I believe that the focus needs to be shifted towards creating a strong brand if Huawei Technologies needs to keep its foothold in the global telecom market. Thus strengthening of the Huawei brand has become even more important. Remodeling to establish Huawei as a brand has been now the new focus to develop a better perceived quality create brand equity. The need of brand recognition has also become very vital to be seen as a valued collaborator for its customers. Brand development has never been big in China; with large volume market brand recognition never existed in the Chinese market. Hence it becomes more essential as well as difficult for Huawei to develop its brand image to compete in the global economy. The strong need for branding and change for the marketing orientation to move towards the service sector becomes more vital when we look into the 5C’s of Huawei Technologies. Issue 4- The 5C’s. Exploring the 5 C’s of Huawei Technologies highlights the core competencies of Huawei and helps us in understanding why a new orientation approach is required . As discussed earlier Huawei Technologies dominates in cost differentiation and is armed with a strong RD to achieve customization in a high barrier industry and it has been a key strength of Huawei Technologies. But a quick SWOT analysis brings out the lack of perceived quality in the market as one of the greatest threats Huawei Technologies faces. Its major competitor Ericsson currently leading the market share comes with a very strong branding and high perceived quality. The dilemma is not just the market perception but also the perception of the employees themselves despite the fact that human capital is a key resource strength of Huawei Technologies which also drives to low labor costs.

Alcohol Policy Done Wrong :: Argumentative persuasive Alcohol Policy Essays

Alcohol Policy Done Wrong When I was elected Interfraternity Council Treasurer in December of 1997 I knew I was in for a long semester, but I never knew what might evolve. I was elected in the wake of alcohol problems across the country. The only alcohol problem I knew of that had happened at the University of Arkansas involved a fraternity on bid day (the day when new freshman receive their invitation to a fraternity house). It involved two students that drank so much alcohol that they had to be rushed to the hospital. Both students were released from the hospital and the fraternity was placed on alcohol probation. I happened to be a newcomer to that fraternity as well and all alcohol probation meant to the fraternity was that they had to be a little more careful about where they drank alcohol in the house. The University of Arkansas has been very lenient in the past about enforcing the alcohol policy. The University’s policy is dated February 22, 1974. The policy states, â€Å"Possession and use of intoxicants in public areas of University facilities (including organized houses) and at official University functions held on campus is prohibited. Persons of legal age as prescribed by state law regarding alcoholic beverages may possess and consume these beverages in the privacy of assigned student rooms. Irresponsible behavior while under the influence of intoxicants is not condoned and may be subject to review and/or action by the appropriate judicial body.† There has been a lot of criticisms to the alcohol policy. First, the fact that it was written in 1974 attracts a plethora of criticisms. I feel that many things have changed since the 70’s and the alcohol policy should also change. Another thing that attracts criticism is the way it has been forced. I hav e seen pictures in the University of Arkansas yearbook from 1970 that show members of fraternities sitting on the roofs of their houses drinking beer out of the can, which is a direct violation of the alcohol policy. I have also heard rumors that in the 80’s kegs were clearly present throughout the fraternity houses. The next thing I would like to mention is the sudden change in enforcement of this alcohol policy. I have been on this campus for three years and I have seen an abrupt change in the way administrators enforce the alcohol policy.

Biology Sensitivity Lab Report

To investigate the effect of skin sensitivity In response to cold temperature in different parts of the body by timing the maximum amount of time in which Ice-pack can be held to that area. Hypothesis: If the layer of skin Is relatively thin, the nerve response to cold will be the fastest, Increasing the skin's sensitivity. This therefore means that the fastest responses to cold will be in the face, and specifically the nose.The skin consists of 3 main layers; the epidermis, dermis and hypodermic (also known as the subcutaneous). The epidermis consists of dead and nearly dead skin cells which protects us from injury, infections, fluid loss†¦ Acting as a barrier. The Dermis is the skin layer which contains most of the nerve cells, hair follicles, sweat glands and many others. The Hypodermic layer is not really a skin layer, it attaches the skin to everything else; it contains the fat layer.The layer of fat in the nose's hypodermic is very thin in relation to other parts of the bo dy which will make the nerves detect the change in temperature on the surface the fastest, therefore bringing upon the response In less time. Variables: Independent variable: The part of the body (area of skin). Dependent variable: The maximum amount of time the ice-pack can be held to the skin (Using a stopwatch).Controlled variables: * The same height group (1 55-CACM) * The same weight group (45-keg) * The same age group (15-20) * The same sex (female) * The same temperature of the Ice-pack (placed In the freezer for 5 hours) * The same surrounding temperature (20-ICC) The same body temperature (3709 ; The same material used in the icepack( plastic and gel) ; The same size and thickness of the icepack (medium sized) Fair test: This experiment is considered to be a fair test because I think that most of the rabbles that can manipulate the results in any way other than the variable which I want to manipulate which is area of skin being tested, for example the height group and age g roup are controlled which ensures that the layer of fat in different people is similar due to these characteristics. Materials: * 3 ice-packs of the same temperature * Stopwatch * Thermometer * A long table Method: 1 . Place 3 identical icepacks in the freezer for 2 hours before starting the 3. Take their temperature making sure it is around ICC (If not change one of the people to one with all the requirements including temperature). 4. Make the person lay on the table on her back. 5.Take out one of the icepacks from the freezer. 6. Place the icepack on the thigh and time the time needed for the person to reach his limits with the cold. 7. Repeat the above step for the other body parts (Upper arm, belly, forearm, forehead and nose). 8. Replace the ice pack in the freezer again and take out another one. 9. Repeat the experiment on the same person another time. 10. Replace the second ice pack and repeat the step above with the third icepack. 11. Replace the ice pack in the freezer. 12 . Wait for an hour to regulate the temperature of the ice packs in the freezer. 13. Repeat steps 3-10 for the second female. 14. Record the result throughout the whole process. 15.The results are not completely constant though since the belly normally has more fat than the upper arm, but since the belly was covered with a shirt beforehand this led to tampering in the reliability of the experiment which is noninsured a source of error. The thermo receptors face's skin is the most responsive to temperature changes; the forehead had an average response time of 17 seconds. I came up with an average for each person's tree trials first, and then I came up with a final set of data for the average of all 6 trials on the two people. I came up with the final average by adding up all the 6 results from the several trials and divide them by 6 giving us a final result that we can work with to draw conclusions about our results and their reliability. Data presentation: Conclusion:My main conclusi on from this experiment about skin sensitivity in different areas in response to cold temperature changes is that the skin on the nose is the most affected. This is because of two things, the main reason being the layer of fat on the nose is a lot thinner than the layer of fat on other parts of the body like the thigh and the second reason being that thermo receptors which are the nerve cells which respond to temperature changes in the surrounding are highly concentrated in the face area so the fastest responses would therefore surely be from the face, explaining the fastest two reactions; nose (an average of 9 seconds) and forehead (an average of 17 seconds). This supports my hypothesis since that was my initial thought regarding the experiments' results due to scientific research.My results are highly valid since they make sense and are backed up with concrete scientific reasoning. The face brought upon the fastest responses followed by the belly and the arm. The belly has a thick er layer of fat than the arm; this is where my results got a bit mixed up since the people tested were wearing shirts which warmed them up fore starting which brought a faster response due to the bigger gap in change of temperature. The thigh had the slowest response time of an average of 163, which is logical since the thigh has the thickest layer of fat between the areas tested. Evaluation: In general I think my method was pretty valid since I controlled all the factors and explained the method in which I did.In my method I also showed steps of finding the average for the data collected which makes my results more reliable since they become more accurate. I also made the person getting tested to lie on a flat surface o that the icepack would be even on her body and won't move or fall down. Sources of error: 1 . The skin temperature was not constant all over the body since the belly for example was covered with a shirt. 2. The Ice-pack got warmer, so the last tests were less reliab le. 3. The pressure applied to the ice-pack was altered and not completely constant. 4. The difference between the reaction time of the forehead Improvements: 1 . The test should only be performed on parts of the body exposed completely, not the ones covered with clothes.

My Classroom Management Plan Essay - 979 Words

A well-managed classroom requires organization and planning. There is nothing more frustrating than a room where you can’t find anything and are unsure of your boundaries. Classroom management begins even before the students enter the classroom on the first day. In order to establish the proper work environment students should have an assignment waiting on their desks as soon as they enter the room. In my case this will be some sort of a tell me about yourself and what you think about science activity. In addition teachers should greet their students at the door with directions for seating and instruction to alleviate some of the confusion that usually plagues classrooms on the first day. It doesn’t matter if teachers†¦show more content†¦I want my students to have a voice in the decisions made within our classroom. In fact, I think the best way to get the year started is with a class discussion of what our rules and consequences will be. I think that if students help set the rules and consequences of the cla ssroom they will have a feeling of ownership. This feeling of ownership will often lead to respect for the classroom rules. Student ownership can also support other aspects of a well-managed classroom. Assigning students in-classroom tasks such as feeding the animals, taking the attendance, putting together absentee packets, etc. will keep students engaged and free up the teacher to handle other classroom management issues. A well-managed classroom requires mutual respect. The term â€Å"respect† has already shown up various times in this piece; that is because it is the key element of classroom management. A classroom founded on respect creates an open and safe environment where the students can have free-exchange of ideas with one another and the teacher. This aspect of management requires constant and consistent enforcement and modeling. Defining what is respectful from the beginning and giving a rationale for treating others with respect is a great way to start. A well-managed classroom requires effective modeling.
