------------------- --------- ---- Name: Division: Quiz #2 ME 200 Prof. Lucht 27 Jan 2012 A gas contained in a piston-cylinder assembly undergoes two processes, A and B, between the same initial state 1, PI = 100 kPa, t71 = 1.0 m 3 , VI = 400 kJ, and the same final state 2, P2 = 1000 kPa, t72= 0.1 m 3 , V 2 = 450 kJ. Process A: Constant volume process from state 1 to state la, where PIa = 10 bar, followed by a constant pressure process to state 2. Process B: P V= constant from state 1 to state 2. Neglect kinetic and potential energy changes. For each process, (a) sketch the process on a P V diagram, (b) calculate the work W l2 in kJ, and (c) calculate the heat transfer Q12 in kJ. Follow the solution procedure we have discussed. List Given, Find, Assumptions, Diagram and System Identification, Basic Equations, Solution, and Solution Check.

### What students are saying

• 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.
