Jntuk 2-1 and 2-2 Mech Syllabus R10

Advantages and disadvantages of alternative energy sources and engineering challenges for the harnessing of such forms of energy will also be addressed along with energy storage and fuel cells. The pre-requisites for the Alternative Energy elective are Thermodynamics II, Fluid Mechanics, and Heat Transfer.

At SVCE, I was first familiarised with the Basic Sciences and Mathematics which provide an ideal foundation for majoring in any branch of Engineering. In Mechanical Engineering, I have been exposed to different areas such as Design, Manufacturing and Solid Mechanics. Some of the courses that I have done to gain understanding in these different areas CAD & CAM, Pro-Engineer and ANSYS. My hands-on experience in CAD and Pro Engineering helped me immensely to complete my pre-final year project on ‘Design and Fabrication of Solenoid Valve’. With the fundamentals in basic subjects I started working on the project and its outcome can be used extensively in fluid applications. I was able to use the fabricated valve in a pipe-circuit prototype and I also explored the

This simple experiment is carried out to show the difference in the enthalpy change of combustion between two fuels, hexane and methanol. These fuels are individually weighed before and after used as heat source to heat water in a calorimeter. The result is used to find out amount of heat transferred by the fuel, amount of fuel used and the enthalpy change of combustion.

Meizu M3 Note finally officially launched outside China. India became the first country to disambangi by phablet successor M2 Note. The price offered by Meizu M3 Note in India turned out to be not much different from the country of origin, that is, $ 150, or about Usd 2 million only. This smartphone is already listed in the online store Amazon India.

The development of mechanical refrigeration systems began in the early19th century and arose mainly from the needs of meat producers in the USA, South America, Australia and New Zealand, who were facing many difficulties in shipping their produce to their export markers in Europe. Many experimental systems were built in the 1830s, utilizing the cooling effect produced by the expansion of

Curled Metal Inc (CMI) is a company whose strategy evolves selling products that used certain types of metal as a raw material. CMI rapidly grow in the last decade due to Slip-Seal, a product that meet the demanding specification of the automaker imposed by US strict environment legislation. In order to diversify offer from auto industry, CMI’s management decided to examine a new application for curled metal technology.

The use of thinner gauge Ti and Ni alloys is pushing the aircraft engine industry to ensure high quality welds can be made with lower levels of heat input. Every part we produce goes through our nondestructive laboratory to test the welds under x-ray or die penetrant.

While my responsibilities included teaching, I spent most of time mentoring 122 students through the test plan development and experiments required by the lab’s seven modules involving topics ranging from material property characterization, flow loop, and performance testing of vacuum cleaners. In addition, I trained new graduate lab assistants; developed two new lab modules addressing industrial safety for operating lathes, drill presses, and milling machines; and developed a presentation on the technical writing skills required for the content and format of the lab reports. Due to my 6 years research and educational background in engineering design, I am interested to teach various courses across the mechanical engineering curriculum including MECH 220 Mechanics, MECH 202 Graphics for Design and Manufacture, MECH 222 Introduction to Mechanical Engineering Lab, MECH 353 Solid Mechanics, MECH 355 Manufacturing Processes, and MECH 302 Finite Elements in Analysis and Design immediately after starting. Moreover, I am interested to teach thermo-fluid courses because my Master of Science concentration was on experimental heat transfer and thermo-fluid sciences.

Air conditioning is an everyday appliance used by all homes and businesses today. It works by utilizing a system of fans and heating/cooling element called ‘freon’ that comes in two types; R-22 and R-410a, R-410a being the newest type of refrigerant that has the advantage of being better for the environment. Despite this, R-410a is not as effective as R-22 in heating/cooling. Air conditioning installations also come in various sizes such as 2-5 ton installations. For instance, 2-ton units will be used in small homes and apartments. Larger 5-ton units will be used for larger installations such as warehouses and offices. Additionally multiple smaller installations could be used on one setup, like 3, 3-ton units being used on a warehouse, and

The diagram in Fig 23.3, on page 1017, displays the air cycle in in a forced air system; in this diagram it displays the cycle of a cooling system. Based on the idea that the refrigerant liquid is being changed from a gas into to liquid when the temperature decreases in the condenser. The liquid then goes into the drier, and then a metering device; which is a control system for the airflow. The liquid then enters the Evaporator, where the temperature increases causing the liquid to change back into a gas state, and expels the cooler air out. The Compressor is adding to the increase in pressure, which changes the boiling point of the refrigerants liquid into vapor form, therefore returning to the condenser to start the process all over again.

I will describe in my own terms how gasoline is used to power the average automobile within an internal combustion engine. I will describe this process from the perspective of thermodynamics. The reason I feel this an interesting topic is the automobile has become such a steady presence in the daily life of society over the past century that we often take for granted the amount of science and engineering that go into them. The thermodynamics involved are a direct daily application of the topics we covered in this course, it also applies concepts we learn in other courses. It’s also an important discussion, because what makes gasoline the most common fuel, how do the alternatives stack up? Or should we look at engines that

Imagine sitting at home in the middle of July. Now, imagine if that day had a high temperature of over 100 degrees, and a heat index of over 115 degrees. If you are living in the United States, then you are probably imagining yourself sitting in a room with some sort of air conditioning system keeping you cool. That comfort, however, comes at a price. In 1985, it was discovered that chlorofluorocarbons (CFC’s), one of the main refrigerants used in air conditioning systems, played a substantial role in the depletion of the ozone layer (Farman, Gardiner and Shanklin). CFC’s were ultimately banned as a means of refrigeration, which ushered in the next generation of coolant types known as hydrofluorocarbons (HFC’s). Unfortunately, “systems using these HFCs, however, make a moderate contribution to global warming because of their efficiency and low emission rates.” (Sand, Fisher and Baxter, P.E.). While addressing the issue of the ozone layer, HFCs initiated a new set problems themselves, including having an increased Global Warming Potential (GWP). Despite the negative environmental impacts of the past, the use of refrigerants in home cooling systems should continue.

Thermodynamic power cycles are the origin of the operation of heat engines which supply a majority of the world electric power and also run a majority of motor vehicles. These power cycles can be put into one of two categories; real cycles and ideal cycles. (saylor.org, n.d.)

Due to their low overall thermal efficiencies, gas turbines initially had limited uses. As time has passed, many renovations have been implemented to the gas turbine cycle to make it more efficient. Some modifications include: increasing the turbine inlet temperatures, increasing the efficiencies of turbo machinery components, and adding modifications to the basic cycle. In contrast to the ideal cycle, the actual cycle undergoes unavoidable pressure drops during the heat addition and heat rejection processes. In addition, the actual work input to the compressor is always more than the output and the actual work output of the turbine is less than the work input due to irreversibility. These relationships are displayed in the figures below:

This technology is far less commonly applied to refrigeration than vapor-compression refrigeration is the primary advantages of a Peltier cooler compared to a vapor-compression refrigerator are its lack of moving parts or circulating liquid, very long life, invulnerability to leaks, small size and flexible shape. Its main disadvantage is high cost and poor power efficiency. Many researchers and companies are
