The cycle is shown in figure is followed by an engine made of one mole of perfect gas in a cylinder with a piston. The processes A to B and C to D are isochoric whereas process B to C and D to A are adiabatic, the work done by the engine in one cycle is
(V A = V B = V, V C = V D = 2V and g = 5/3)
A
[1 – 4 3/2 ] (P B – P A ) V
B
[1 – 3 2/3 ] (P B – P A ) V
C
[1 – 2 –2/3 ] (P B – P A ) V
D
[1 – 2 –2/3 ] (P B – P A ) V
