a 10 ft^3 tank is full of liquid refrigerant R-134a at a temperature of 120 F. A valve is opened an allows vapor to be removed from this tank and sent to a reversible and adiabatic turbine to produce work. The temperature in the tank remains constant during the process. the refrigerant leaves the turbine at a pressure of 10 psia. Calculate the amount of work (in Btu) produced by the turbine if half of the mass in the tank...
