There are required 2000 kW of compressor power to handle air adiabatically from 1 atmosphere, 27 °C, to 305 kPaa. The initial air velocity is 20 m/s and the final velocity is 85 m/s. a) If the compression is isentropic, find the compressor capacity, in m3/s. b) If the compression process is irreversible adiabatic to a temperature of 160 °C, with the capacity found in (a), determine the compressor power input, in Hp.
