Unformatted text preview: Page 1 of 1 Problem 2: Air enters a twostage compressor at 100 kPa and 300 K and is compressed to 900 kPa. The pressure ratio across each stage is the same, and the air is cooled by removing 80 kW of heat from the flow between the two stages. Assuming each compressor has an adiabatic efficiency of 0.85, determine the power input to the compressors for a mass flow rate of 1 kg/s. What would your answer be if only one stage of compression were used between the same inlet and exit pressures? Neglect the velocities at both compressor inlets and outlets. Page 2 of 2...
