A 5-hp pump compressor delivers oxygen at a rate of 30 cubic feet per minute. The pressure and temperature of the air at the compressor inlet are 1 atm and 60°F. If no heat was transferred to the gas and the change in potential and kinetic energies can be considered negligible, find the temperature of the oxygen at the compressor outlet in °F. Assume that the specific heat ratio of oxygen gas stays constant at 1.395. ANSWER: 442.6753°F
