A system undergoes three quasi-static processes sequentially as indicated in the given figure. 1-2 is an isobaric process, 2-3 is a polytropic process with = 4/3 and 3-1 is a process in which PV= constant. P2 = P1 = 4 x 105 N/m2, P3 =1 x 105 N/m2 and V1 = 1 m3.
The heat transfer for the cycle is , the change in internal energy is and the work done is . Then
