An insulated tank containing 0.5m3 of R-134 at 500 kPa and 90%quality is connected to an initially evacuated insulatedpiston-cylinder device. The force balance on the piston is suchthat a pressure of 120kPa is required to lift the piston. The valveis then opened slightly and part of the refrigerant flows to thecylinder, pushing the piston up and the final cylinder volume is1.5 m 3 . The process ends when the pressure in the tank drops to120kPa. Assume the refrigerant in the tank undergoes an isentropicprocess. (a) Determine the quality in the tank and the cylinder.0.896, 0.92 (b) Calculate the boundary work 280.8 kJ (Expansion)(c) Determine the entropy generated during the process 0.1973kJ/K
