A gas within a piston-cylinder assembly undergoes through a thermodynamic cycle consisting of three processes:
Process 1-2: Constant volume, V1 in m3; U2 - U1 = 26.4 kJ.
Process 2-3: Expansion considering PVn= constant; U3 = U2.
Process 3-1: Constant pressure, P = 1.4 bar, W31 = -10.5 kJ
(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.
There are no significant changes in kinetic or potential energy at each process.
