A gas within a piston-cylinder assembly undergoes a thrmodynamics cycle consisting of three processes:
Process from state 1 to state2: Compression with U2=U1.
Process from 2 to 3: constant volume cooling to p3= 140 kPa and v3= 0.028m3
Process from 3 to 1: constant pressure expansion with W31=10.5 kj.
The system is stationary, and the cyclic work Wc= -8.3kj. Now sketch the cycle on a pressure-volume diagram, determine the volume at state 1, work and heat transfer for process 1 to 2 and justify that weather this is a power cycle or refrigeration cycle.
