Question

...

A gas within a piston-cylinder assembly undergoes a thermodynamic cycle consisting of three processes: Constant volume, V = 0.028 m2, U2 - U1 = 26.4 kJ. Expansion with pV = constant, U3 = U2. Constant pressure, p = 1.4 bar, W31 = - 10.5 kJ. There are no significant changes in kinetic or potential energy. Sketch the cycle on a p-V diagram. Calculate the net work for the cycle, in kJ. Calculate the heat transfer for process 2-3, in kJ. Calculate the heat transfer for process 3-1, in kJ. Is this a power cycle or a refrigeration cycle?

Explanation / Answer

This is a power cycle. I am posting the solution. DO rate the answer. Thanks. :)
