Polytropic process c and n
WebNitrogen gas is compressed from 80 kPa and 27°C to 480 kPa by a 10-kW compressor. Determine the mass flow rate of nitrogen through the compressor, assuming the compression process to be (a) isentropic, (b) polytropic n=1.3, (c) isothermic, (d) ideal two stages polyropic n=1.3.
