Air undergoes a cycle that is composed of three processes, as shown in Fig. 3.54, with Thigh = 2400 K and vmax /vmin = 6. Assuming quasi-equilibrium processes with constant specific heats, calculate the work for each process and the net heat transfer for the cycle for this piston-cylinder arrangement if P high is
a) 1000 kPa,
b) 750 kPa,
c) 500 kPa.
