Air enters a compressor operating at steady state at a pressure of 1 bar, a temperature of 260 K, and a velocity of 8 m/s through an inlet with an area of 0.25 m2. At the exit, the pressure is 7 bar, the temperature is 450 K, and the velocity is 2 m/s. Heat transfer from the compressor to its surroundings occurs at a rate of 180 kJ/min. Employing the ideal gas model, calculate the power input to the compressor, in kW.
