Air is compressed in an adiabatic compressor. Inlet and outlet conditions are 120kPa, 30 oC and 20 m/s; 1.4 MPa, 530 oC and 80 m/s. The surrounding air temperature is 25 oC. The inlet cross-sectional area is 0.013 m2. Assume Cp = 1005 J/kgK, R = 287 J/kgK, k = 1.4.

Argon (100 kPa and 10 deg C) enters a compressor with a mass flowrate of 0.19 kg/s. It exits at 600 kPa and 130 deg C. The compressor has a specific heat loss of 16 kJ/kg. What is the power (kW) required for the compressor? Report your answer to 2 decimal places.

NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. An adiabatic air compressor compresses 10.4 L/s of air at 120 kPa and 20°C to 1000 kPa and 300°C. The constant pressure specific heat of air at the average temperature of 160°C = 433 K is cp= 1.018 kJ/kg.K. The gas constant of air is R = 0.287 kPa.m³/kg-K. 1 MPa 300°C Compressor 120 kPa 20°C Vus Determine the work required by the compressor. (You must provide an answer before moving on to the next part.) The work required by the compressor is -4.578 kJ/kg.
