Refrigerant-134a enters a compressor as a saturated vapor at 160 kPa at a rate of 0.03 m3/s and leaves at 800 kPa. The power input to the compressor is 10 kW. If the surroundings at 20C 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.

Refrigerant-134a enters a compressor as a saturated
vapor at 160 kPa at a rate of 0.03 m3/s and leaves at
800 kPa. The power input to the compressor is 10 kW. If
the surroundings at 20C 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.
