A steam compressor receives H 2O at 90kPa and 75% quality at a rate of 50 kg/s. Part way through the compressor, steam is bled off at 20kg/s, 2MPa and 300C. The remainder exits the compressor at 10MPa, 500C. Assuming heat transfer and changes in potential and kinetic energies are negligible, find the power input to the compressor.
