Air enters a compressor operating at steady state at 1.05 bar, 300 K, with a volumetric flow rate of 66 m3/min and exits at 12 bar, 400 K. Heat transfer occurs at a rate of 11 kW 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 kW. Wev = i kW
