Process1-2: Constant temperature expansion at 600 K from P1=0.5MPa tp P2=0.4MPa
Process 2-3: Polytropic expansion with n=1.4 to P30.3MPa
Process 3-4: Constant-pressure compression to V4=V1
Process 4-1: Constant volume heating.
For the cyle
a) Sketch the cycle on a P-v diagram
b) compute the work and heat transfer per unit mass for each process in, kj/kg, and the entropy production, in kj/k, and
c) determine the thermal efficiency of the cycle and compare to the Carnot efficiency.
