There is an air compressor. The air temperature and pressure flowing into the compressor are 20℃ and 80kPa. At the outlet of the compressor, the pressure is 800 kPa and the temperature is 200℃. When the required power of the compressor is 400kW, find the heat rate (Q)[kW]. Compressor outlet inner diameter is 10cm, flow speed is 20m/s.

Air at a pressure of 101 kPa and temperature of 288 K enters an axial compressor stage with a velocity of 170 m/s. There are no guide vanes, so the air enters in the axial direction only. When traveling through the rotor, the air turns 15 degrees. This means the angle of the relative velocity with respect to the axis is 15 degrees greater when entering the rotor than when it leaves. The rotor spins at 8000 rpm and has...
