Question: Refrigerant-134a enters a compressor as a saturated vapor at 200 kPa at a rate of 0.03 m3/s and leaves at 700 kPa. The power input

Refrigerant-134a enters a compressor as a saturated vapor at 200 kPa at a rate of 0.03 m3/s and leaves at 700 kPa. The power input to the compressor is 10 kW. If the surroundings at 20°C experience an entropy increase of 0.008 kW/K determine
(a) The rate of heat loss from the compressor,
(b) The exit temperature of the refrigerant, and
(c) The rate of entropy generation.
