A single cylinder, single acting reciprocating compressor using R-12 as refrigerant has a bore of 80 mm and a stroke of 60 mm. The compressor runs at 1450 rpm. Assuming no clearance and if the suction temperature is 10⁰C and condensing temperature is 50⁰C, (a) determine: (i) the refrigeration capacity (ii) the power per kW of refrigeration (iii) the total power required to drive the compressor (b) If the clearance factor of 5% is to be considered, determine: (i) mass of refrigerant circulated in kg/s (ii) refrigerating capacity (iii) the power per kW of refrigeration (iv) the total power required to drive the compressor
