cycle is executed by 2 kg of R-22 in a piston-cylinder assembly. The cycle consists of the following internally reversible processes: 1-2 heat removal at constant pressure 2-3 adiabatic expansion to 6 bar 3-4 heat addition at constant pressure 4-1 adiabatic compression to 14 bar. State 1 is saturated vapor, and state 2 is saturated liquid. TEST is recommended for this problem, but it is also possible to solve with tables
