Answer published by the source. Consult the official source to check your work against its answer.
question
A reciprocating refrigeration compressor uses Freon-12 as the refrigerant. The gas enters at 20lbf/in^2, 60°F and is compressed to 180lbf/in^2. The single cylinder compressor has a bore of 2.0 in, a stroke of 2.5 in and a rpm of 1800. Calculate the volumetric efficiency of this compressor if the mass rate of flow of refrigerant is 2.5lbm/min.
