a vapor-compression refrigeration system uses R-134a. the evaporator pressure is 200.60 kPa and a condenser pressure of 770.20 kpa. The refrigerant enters the compressor as a saturated vapor and leaves the condenser as subcooled liquid at 20C (there is subcooling from Tsaturated to 20C)

Question
a vapor-compression refrigeration system uses R-134a. the evaporator pressure is 200.60 kPa and a condenser pressure of 770.20 kpa. The refrigerant enters the compressor as a saturated vapor and leaves the condenser as subcooled liquid at 20C (there is subcooling from Tsaturated to 20C)
(a) The flowrate of R-134a in kg/s, if the refrigeration capacity is 35.5 kW
(b) Work requirement in the compressor in KJ/Kg, if the compressor efficiency is 0.80
(d)P-H diagram of the cycle
