Air enters a compressor operating at steady state at 15.4 lbf/in^2, 80°F with a volumetric flow rate of 424 ft^3/min and exits at 176.4 lbf/in^2, 260°F. Heat transfer occurs at a rate of 6800 Btu/h from the compressor to its surroundings. Assuming the ideal gas model for air and neglecting kinetic and potential energy effects, determine the power input, in hp.
