Extracted text: 3.37 As shown in Fig. P3.37, Refrigerant 134a is contained in a piston-cylinder assembly, initially as saturated vapor. The refrigerant is slowly heated until its temperature is 160°C. During the process, the piston moves smoothly in the cylinder. For the refrigerant, evaluate the work, in kJ/kg. - Weight = 471.1 N D= 0.02 m Patm = 1 bar Piston Initial: Saturated vapor Final: T2 = 160°C Refrigerant 134a Fig. P3.37
