Refrigerant-134a of mass 1 kg undergoes two processes in series in a piston-cylinder assembly. at the initial state, the refrigerant is saturated vapour at a pressure of 25 bar. process 1-2: isothermal compression until all the mixture becomes saturated liquid. process 2-3: the refrigerant is cooled at constant volume to a pressure of 18 bar. a. sketch the processes on p-v and t-v diagrams, indicating clearly the path and direction of the processes determine: i. the specific volume and specific internal energy of the refrigerant at b. ii. iv. v. the end of the isothermal process. the state of the refrigerant at the work done in each process, in kj. the heat transfer in each process, in kj. (0.0010566 m3/kg, 166.99 kj/kg, 0.966 %,-14.699 kj, 0 kj,-111.159 kj,-23.52 kj)
