Question:

Two kilograms of air undergo a cycle that is composed of three processes, as shown in Fig. 3.56. Assuming quasi-equilibrium processes and constant specific heats, calculate the work for each process and the net heat transfer for the cycle for this piston-cylinder arrangement if Phigh is
a) 1000 kPa,
b) 750 kPa,
c) 500 kPa.
