A gas within a piston-cylinder assembly undergoes a thermodynamic cycle consisting of three processes:
Process 1-2: Constant volume V1 = 2 m3, p1 = 1 bar, to p2 = 3 bar, U2 – U1 = 400 kJ.
Process 2-3: Constant pressure compression to V3 = 1 m3.
Process 3-1: Adiabatic expansion, with W31 = 150 kJ.
There are no significant changes in kinetic or potential energy. Determine the net work for the cycle, in kJ, and the heat transfers for Processes 1-2 and 2-3, in kJ. Is this a power cycle or refrigeration cycle? Explain
