Please help!!!!
Refrigerant 22 enters the compressor of an ideal vapor-compression refrigeration system as saturated vapor at -30°C with a volumetric flow rate of 10 m3/min. The refrigerant leaves the condenser at 19°C, 9 bar.
Determine:
(a) the magnitude of the compressor power, in kW.
(b) the refrigerating capacity, in tons.
(c) the coefficient of performance.
(d) the rate of entropy production for the cycle, in kW/K.
Answer for part (a): 52 kW
Answer for part (b): 59 tons
Answer for part (c): 3.98
Please answer part also d! That's the part I also need. Thank you!
