An isentropic compressor compresses r-134a initially at 140 kpa and -10c∘ to 1000 kpa at a rate of 1.33 kg/s. what is the temperature of the r-134 when it exits the compressor in c? how much power is needed to run this compressor in kw?

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
