Q2: an ammonia vapour compressor refrigerator has a single acting stage, single acting reciprocating compressor which has a bore of 127 mm, a stroke of 152 mm and speed 240 rpm. The pressure in the evaporator is 1.6 bar and that in condenser is 13.9 bar. The volumetric efficiency of the compressor is 80% and mechanical efficiency is 90%. The vapour is dry saturated on leaving evaporator and liquid leaves the condenser at 32 "C. Calculate the mass flow rate of the refrigerant and the power ideally required to drive the compressor?
