Air is compressed steadily by a compressor from 100 kPa and 27°C to 800 kPa and 300°C. The mass flow rate of the air is 10 kg/min. During the process, the heat is lost from the compressor at a rate of 5 kW to the surrounding at 27°C. Assume air to be an ideal gas and the changes in kinetic and potential energies can be neglected. Q4 a) Determine the power required by the compressor, kW. b) Find the minimum power required by the compressor, c) Calculate the isentropic efficiency of the compressor, %. kW.
