Air enters a compressor operating at steady state at a pressure of 1 bar, a temperature of 290K and a velocity of 6 m/s through an inlet with an area of 0.1m?. At the exit, the pressure is 7 bar, the temperature is 450K and the velocity is 2m/s. Heat transfer from the compressor to its surroundings occurs at the rate of 180KJ/min. Employing the ideal gas model, calculate the power input to the compressor, in Kw. (H, =290.16KJ / kg and H, = 451.8KJ / kg)
