Consider a compressor which is adiabatic. At the inlet of the compressor the temperature is 360 K and pressure is 130 kPa and the air passes at the rate of 1 kg/s. At the exit of the compressor the temperature is 550 K and pressure is 900 kPa. Find the volumetric flow rate of air at the exit [m³/s] and also, power consumed by the compressor [kW]. Assumptions. Steady state process. Kinetic and potential energy changes are negligible. Air is an ideal gas with variable specific heats.
