A gas undergoes a thermodynamic cycle consisting of three processes :
Process 1-2 : compression with pV=constance , from p1 = 1 bar , v1 = 1.6 m3 to v2=0.2 m3 , u2-u1=0
Process 2-3 : constance presure to v3 = v1
Process 3-1 : constance volume , u1 - u3 = -3549 KJ
There are no significant changes in kinetic or potential energy. Determine the heat transfer and work for Process 2-3 , in KJ. It this a power cycle or a rerigeretion cycle?
