11- Air enters a compressor operating at steady state with a pressure of 1 bar, a temperature of 20C, and a volumetric flow rate of 0.25 m'/s. The air velocity in the exit pipe is 210 m/s and the exit pressure is 1 MPa. If each unit mass of air passing from inlet to exit undergoes a process described by pv34 = constant, determine the exit temperature, in C.
