BMCT 2713 THERMODYNAMICS I TUTORIAL 06 FACULTY OF MECHANICAL ENGINEERING BMCT 2713THERMODYNAMICS I TUTORIAL 06 1. The entropy of a hot baked potato decreases as it cools. Is this a violation of the increase of entropy principle? Explain. 2. Is it possible to create entropy? Is it possible to destroy it? 3. Is it possible for the entropy change of a closed system to be zero during an irreversible process? Explain. 4. Air is compressed by a 12 kW compressor from P 1 to P 2 . The air temperature is maintained constant at 25 o C during this process as a result of heat transfer to the surrounding medium at 10 o C. Determine the rate of entropy change of the air. State the assumption made in solving this problem. 5. During the isothermal heat addition process of a Carnot cycle, 900 kJ of heat is added to the working fluid from a source at 400 o C. Determine: a) The entropy change of the working fluid b) The entropy change of the source c) The total entropy change for the process.

"Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
