Refrigerant-134a enters a compressor as a saturated vapor at 150 kPa at a rate of 0.05 m/s and leaves at 900 kPa. The power input to the compressor is 10 kW. If the surroundings at 25C experience an entropy increase of 0.008 kW/K. Determine: (i) the rate of heat loss from the compressor (units: kW), (ii) the mass flow rate of the refrigerant (units: kg/s) [Marks=7%] [Marks=5%] (iii) the exit temperature of the refrigerant, and (units: K) [Marks=7%] (iv) the rate of entropy generation (units: kW/K).
