7-85 An ideal gas at 100 kPa and 27°C enters a steady-flow compressor. The gas is compressed to 400 kPa, and 10 percent of the mass that entered the compressor is removed for some other use. The remaining 90 percent of the inlet gas is compressed to 600 kPa before leaving the compressor. The entire compression process is assumed to be reversible and adiabatic. The power supplied to the compressor is measured to be 32 kW. If the ideal gas has constant specific heats such that cv = 0.8 kJ/kg . K and cp = 1.1 kJ/kg . K, a) sketch the compression process on a T-s diagram, b) determine the temperature of the gas at the two compressor exits, in K, and c) determine the mass flow rate of the gas into the compressor, in kg/s. | |
