Applying the Entropy Balance: Control VolumesRefrigerant
Chapter 6, Problem 103P(choose chapter or problem)
Refrigerant 134a at \(30 \mathrm{\ lbf} / \mathrm{in} .^{2}, \ 40^{\circ} \mathrm{F}\) enters a compressor operating at steady state with a mass flow rate of 150 lb/h and exits as saturated vapor at \(160 \mathrm{\ lbf} / \mathrm{in} .^{2}\) Heat transfer occurs from the compressor to its surroundings, which are at \(40^{\circ} \mathrm{F}\). Changes in kinetic and potential energy can be ignored. A power input of 0.5 hp is claimed for the compressor. Determine whether this claim can be correct.
