= = A piston cylinder assembly contains m1 = 25 kg of refrigerant R134a that is initially at P 400 kPa with a quality of x1 = 0.80. The valve is opened between the cylinder and the supply line that carries R134a at Ts 120°C and Ps = 1 MPa, allowing R134a to enter the cylinder. The pressure remains constant during this process. The valve is closed when all of the R134a in the cylinder has been vaporized. The work produced during this process is 300 kJ. a) Calculate the mass of R134a that enters the cylinder b) Calculate the heat transfer in this process. c) Assuming the surrounding temperature is 300 K, Calculate the entropy produced in this process.
