A gas undergoes a thermodynamic cycle consisting of three processes: Process 1 2: constant volume, V = 0.028 m3, U2 - U1 = 26.4 kJ Process 2 3: expansion with pV = constant, U3 = U2 Process 3 1: constant pressure, p = 1.4 bar, W31 = -10.5 kJ There are no significant changes in kinetic or potential energy. (a) Sketch the cycle on a p V diagram. (b) Calculate the net work for the cycle, in kJ. (c) Calculate the heat transfer for process 2 3, in kJ. (d) Calculate the heat transfer for process 3 1, in kJ. (e) Is this a power cycle or a refrigeration cycle?
