Air is compressed steadily by a compressor from 100 kpa and 17°c to 700 kpa at a rate of 5 kg/min. determine the minimum power input required if the process is
(a) adiabatic and
(b) isothermal. assume air to be an ideal gas with variable specific heats, and neglect the changes in kinetic and potential energies.
