In conclusion, I have gained more insight into what it’s like to be a mechanical engineer. I would like to thank Mr. Kele for the speech and Prof. Raji Lukoor for arranging the speaker event for us. I would highly recommend Mr. Kele for future speaker…
Mechanical Engineering is the application of the principles of science and mathematics to a design of machinery and equipment used in transportation, manufacturing and energy conversion.The following annotated bibliography contains three sources related to the Mechanical Engineering major. The three sources will include a scholarly journal, a book, and a lab report, with different topics, but all relating to my academic discourse community. The scholarly journal is about a mechanical hand and it covers the basics on how it works without getting too overwhelming. The second source will be a textbook for a general chemistry class, where students are able to learn how to be literate with science. And for third and final source will be a lab report…
Air-standard analysis treats the fluid flow through the entire engine as air and approxi¬mates air as an ideal gas. In a real engine inlet flow may be all air, or it may be mixed, up with 7% fuel, either gaseous or as liquid droplets, or both. In air-standard analysis, even if all fluid in an engine cycle were air, some error would be introduced by assuming it to be an ideal gas with constant specific heats. At the low pressures of inlet and exhaust, air can accurately be treated as an ideal gas, but at the higher pressures during combustion, air will deviate from ideal gas behavior. A more serious error is introduced by assuming constant specific heats for the analysis. Spe¬cific heats of a gas have a fairly strong dependency on temperature and can vary as much as 30% in the temperature range of an engine. During the cycle of a real engine there are heat losses which are neglected in air-standard analysis. Loss of heat during combustion lowers actual peak temperature and pressure from what is predicted. The actual power stroke, therefore, starts at a lower pressure, and work output during expansion is decreased. A detailed study of the performance of a reciprocating internal combustion engine would take into account many features. These would include the combustion process occurring within the cylinder and the effects of irreversibility have associated with friction and with pressure and temperature gradients. Heat transfer between the gases in the cylinder and the cylinder walls and the work required to charge the cylinder and exhaust the products of combustion also would be considered. Owing to these complexities, accurate modeling of reciprocating internal combustion engines normally involves computer simulation. To conduct elementary thermodynamic analyses of internal combustion engines, considerable simplification is required. One procedure is to employ an air-standard analysis having the following…

The AAP Graduate Mentor Program provides assistance in reviewing your Statement of Purpose for graduate school applications. Graduate student mentors offer constructive suggestions on your statement of purpose and also provide samples of previous statements from successful applicants. To serve your needs better, we require that you bring a first draft of your statement of purpose at least one month before your application deadline. Make it concise and limit the statement to one or two pages. This step by step outline has been considered effective by many advisers in the graduate school application process. What follows is a basic format of what your statement should include.…
Statement of Purpose My decision to pursue graduate study in the United States is underscored by my great desire to be a part of the graduate program at your institution. I am very fortunate to find that the University of Pittsburgh is offering a Master of Science in Health and Rehabilitation Sciences with a structured Physical Therapy concentrated program. I am keen to enroll in this program with a focus on neuromuscular approach due to my previous academic studies as well as work experience in the field. Joining the program would prepare me to become a specialized clinician and a future educator.…
Mechanical engineers are connected with the production and processing of energy and with providing the means of production, the tools of transportation, and the techniques of automation. The skill and knowledge base are extensive. Among the disciplinary bases are mechanics of solids and fluids, mass and momentum transport, manufacturing processes, and electrical and information theory. Mechanical engineering design involves all the trainings in mechanical engineering. Real problems resist compartmentalization. A simple journal bearing involves fluid flow, heat transfer, friction, energy transport, material selection, thermo mechanical treatments, statistical descriptions, and so on.…
Ther is a saying: “My purpose in life is to have a life with purposes” is a quote I lived by throughout many years. I think it is very important to have goals and to accomplish those goals a well as you can. I am forty seven years old, I am married and Father of two children, We have many purposes, one of them is their education , their health, but we also know that we don’t have enough time nor enough education to supply all their demands, and the many things that the current system demands. My new purpose is my graduation as Electrical Engineering Technology in Penn Foster College, perhaps It gives me the opportunity…
In addition to the academic interests, I have undergone an intensive training in CNC Milling, Programming and Operation with FANUC O-M Control at Advanced Training Institute (ATI) Chennai, which is one of the best training centres in the country. I have also attended a workshop on 'automotive sketching and car styling' held at Chennai. To present my knowledge of engineering, I have presented two papers, one on "Intelligent vehicle technology" and the other on "Enhancement of CHF in pool boiling using nanofluids" which was selected for National conference held at B.I.T.M, Bellary. To exhibit my skills of designing, I have participated in National Design competition '14 conducted by CADD Centre. These features in my undergraduate study have given me an insight into the ins and outs of Mechanical engineering principles and fundamentals.…
Thermodynamics is the science which has evolved from the original investigations in the 19th century into the nature of “heat.” At the time, the leading theory of heat was that it was a type of fluid, which could flow from a hot body to a colder one when they were brought into contact. We now know that what was then called “heat” is not a fluid, but is actually a form of energy – it is the energy associated with the continual, random motion of the atoms which compose macroscopic matter, which we can’t see directly. This type of energy, which we will call thermal energy, can be converted (at least in part) to other forms which we can perceive directly (for example, kinetic, gravitational, or electrical energy), and which can be used to do useful things such as propel an automobile or a 747. The principles of thermodynamics govern the conversion of thermal energy to other, more useful forms. For example, an automobile engine can be though of as a device which first converts chemical energy stored in fuel and oxygen molecules into thermal energy by combustion, and then extracts part of that thermal energy to perform the work necessary to propel the car forward, overcoming friction. Thermodynamics is critical to all steps in this process (including determining the level of pollutants emitted), and a careful thermodynamic analysis is required for the design of fuel-efficient, low-polluting automobile engines. In general, thermodynamics plays a vital role in the design of any engine or power-generating plant, and therefore a good grounding in thermodynamics is required for much work in engineering. If thermodynamics only governed the behavior of engines, it would probably be the most economically important of all sciences, but it is much more than that. Since the chemical and physical state of matter depends strongly on how much thermal energy it contains, thermodynamic principles play a central role in any description of…
