Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 57 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 9.5 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.
