Air enters a compressor operating at steady state at 1.05 bar, 300 K, with a volumetric flow rate of 21 m³/min and exits at 12 bar, 400 K. Heat transfer occurs at a rate of 3.5 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.
