A gas within a piston-cylinder assembly undergoes a thermodynamic cycle consisting of three processes:
Process 1->2
Compression with pV=consant, from p1=1 bar, V1=2 meters cubed, to V2=0,2 meters cubed, U2-U1=100kJ
Process 2->3
Constant Volume to p3=p1
Process 3->1
Contant Pressure and adiabatic process
There are no significant changes in kinetic or potential energy. Determine the net work of the cycle, in kJ, and the heat transfer for process 2-3, in kJ, Is is this a power cycle or a refrigeration cycle? Explain.
