Cycle problem, Energy and first law of Thermodynamics, Moran Chapiro
A gas undergoes a thermodynamic cycle consisting of three processes:
Process C–B: constant volume, V = 0.028 m3
Process B–A: expansion with pV = k = constant, UA = UB, UB – UC = 26.4 kJ
Process A–C: constant pressure, p = 1.5 bar, WAC = 10.5 kJ
There are no significant changes in kinetic or potential energy.
(a) sketch the p-v diagram of the cycle
(b) Calculate the net work for the cycle, in kJ.
(c) Calculate the heat transfer for process B–A, in kJ.
(d)Calculate the heat transfer for process A–C, in kJ.
Is this a power cycle or a refrigeration cycle?
