A turbine operating at steady state enters refrigerant 134a at 10 bar, 70C, and 35 m/s throughan inlet with a cross section of 32 cm. At the outlet the conditions are 1 bar, 0C and 75 m/s. The power developed is 200 kW. Determine (a) the mass flow of refrigerant in kg/s, (b) the heat flow in kW and (c) the outlet area in cm.
