10) Steam enters a turbine with a mass flow rate of 15 kg/s at 600C and 7 MPa. 20% of the steam is removed in the middle of the turbine where the pressure is 200 kPa. The remainder of the steam leaves turbine exit at 20 kPa. If the isentropic efficiency of the turbine is 85%, what is the total power generated by this turbine? 11) Air enters a compressor with a pressure of 20 psia, a temperature of 100F, and a volumetric flow rate of 10 ft/s, and exits the compressor at 80 psia. If the isentropic efficiency of the compressor is 85%, what is the power input required for this compressor? 12) Saturated liquid refrigerant 134a at 800 kPa is throttled to a pressure of 100 kPa. What is the entropy change during this process?
