## Homework Statement

Air enters a compressor operating at a steady state with a pressure of 14.7 psi, a temperature of 70 F , and a volumetric flow rate of 500 ft^3/min. The air velocity in the exit pipe is 700ft/s and the exit pressure is 120 psi. If each unit mass of air passing from the inlet to the exit undergoes a process described by pv^1.34= constant determine the exit temperature on F and the diameter of the exit pipe in inches. What is the isentropic efficiency of the compressor?
