A gas within a piston-cylinder assembly undergoes a thermodynamic cycle consisting of three processes:

Process 1-2: Constant volume, V = 0.028 m^3, 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.

Is this a power cycle or a refrigeration cycle?
