Problem 2: Air enters a compressor operating at steady state with a pressure of 14.7lbf/in2, a temperature of 80F, and a volumetric flow rate of 18ft3/s. The air exits the compressor at a pressure of 90 lbf/in2. The heat transfer from the compressor to its surroundings occurs at a rate of 9.7BTU/lb of air flowing. The compressor power input is 90hp. Neglecting kinetic and potential energy effects and modeling air as an ideal gas, determine the exit temperature, in F
