In a vapor-compression refrigeration cycle, ammonia exits the evaporator as saturated vapor at -22°c. the refrigerant enters the condenser at 16 bar and 160°c, and saturated liquid exits at 16 bar. there is no significant heat transfer between the compressor and its surroundings, and the refrigerantpasses through the evaporator with a negligible change in pressure. if the refrigerating capacity is 150kw, determine: (a) the mass flow rate of the refrigerant, in kg/s.(b) the power input to the compressor, in kw.(c) the coefficient of performance.(d) the isentropic compressor efficiency(e) the rate of entropy production, in kw/k, for the compressor.
