1) 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? 2) Saturated liquid refrigerant 134a at 800 kPa is throttled to a pressure of 100 kPa. What is the entropy change during this process?
