------------------- --------- ---- 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.

    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.
