Refrigerant 134a at p1 = 30lbf/in2, T1 =40oF enters a compressor operating at steady state witha mass flow rate of 400 lb/h and exits as saturated vapor atp2 = 160 lbf/in2. Heattransfer occurs from the compressor to its surroundings, which areat T0 = 40oF. Changes in kinetic andpotential energy can be ignored. The power input to the compressoris 4 hp. Â
Determine the heat transfer rate for the compressor, in Btu/hr, andthe entropy production rate for the compressor, inBtu/hr·oR.
