You have a refrigerant 134-a in the vapor state within a cylinder-plunger arrangement. The refrigerant undergoes a change of state when going from a state 1, where T = 28.53 °C and u = 233.88 kj / kg, to a state 2, where T = 55 °C and u = 265.32 kJ / kg. During the process, the cylinder transfers 500 Kj / kg in the form of heat to the surroundings. Find the work per unit mass done on the refrigerant.
