Extracted text: d. 31 е. 40 Q25-26. An adiabatic diffuser in a jet engine is designed to decrease the kinetic energy of the air entering the engine compressor. If air enters at 100 kPa and 30°C with a velocity of 350 m/s and the exit state is 200 kPa and 90°C, using C, = 1.007 kJ/kgK Q25. The net heat transfer by the compressor is: a. 8 kW b. 18 kW c. 22 kW d. O kW e. 50 kW
