Agas within a piston-cylinder assembly undergoes a thermodynamic cycle consisting of three processes: process 1-2: compression with pv = constant, from p1 = 1 bar, v1 = 2 m3 to v2 = 0.2 m3 , u2 - u1 = 100 kj. process 2-3: constant volume to p3 = p1. process 3-1: constant-pressure and adiabatic process. there are no significant changes in kinetic or potential energy. determine the net work of the cycle, in kj, and the heat transfer for process 2-3, in kj. is this a power cycle or a refrigeration cycle? explain. (hint: evaluating whether the work is done by or on the system should answer the question of what type of cycle this is.)
