Question: air at a temperature of 50 c and pressure 1...

Question details

Air at a temperature of 50 °C and pressure 1 atm enters a steady state gas compressor with an inlet volumetric flow rate of 6m^3/min and is compressed to 6 atm. ignore the change of KE and PE, assume heat transfer occurs at a boundary temperature of 27 °, Molecular weight for air is 29 g/mol

1) calculate the mass flow rate of the air at the inlet in kg/s

2) determine the minimum work required (kW) for this compressor assuming isothermal operation.
