Apiston cylinder assembly contains air undergoes a cycle consisting of four process in series process 1-> 2: constant-temperature expansion at 600 k from p 0.5 mpa to p2 0.4 mpa process 2-> 3: polytropic expansion with n 1.4 to ps 0.3 mpa. process 3-4: constant-pressure compression to v4 vi process 4> 1: constant-volume heating. sketch the cycle on a p - v diagram. determine (a) the work and heat transfer for each process, in kj/kg, and (b) is it a power cycle or a refrigeration heat pump cycle? p, t, v (m/kg) and u in addition to what has been asked in the problem state all the properties (kj/kg) for states 1,2,3 & 4. also sketch the cycle in a t- v diagram.
