thermodynamic cycle

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

Process 1–2: Constant volume, V 5 0.028 m3, U2  2 U1      5

26.4 kJ.

Process 2–3: Expansion with pV 5 constant, U3 5 U2.

Process 3–1: Constant pressure, p 5 1.4 bar, W31  5 210.5 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?
