An ammonia compressor operates at an evaporator pressure of 316 kPa and a condenser pressure of 1514.2 kPa. The refrigerant is subcooled 5 degrees and is superheated 8 degrees. A twin-cylinder compressor with bore to stroke ratio of 0.85 is to be used at 1200 rpm. The mechanical efficiency is 77%. For a load of 87.5 kW, determine: (a) the volume flowrate of cooling water in the condenser if the increase in temperature is 7 degrees, (b) the bore and stroke, (c) the size of the driving motor, and the quality of the refrigerant entering the evaporator (d)
