STEP:1 p1=100kpa t1=300k 1-2constant volume process workdone=zero STEP: 2 p2=400k Find  t2 p1v1t1=p2v2t2 Since v1=v2 Find t2 STEP: 3 2-3 is entropic process work done= mR(T2−T3)1−n where n=1.28 STEP: 4 To find t3 from the below equation. (T1T3)=(p1p2)nn−1 STEP: 5 3-1 constant pressure prosses workdone=  mR(t1−t3)
