Question at position 1 In a jet engine a diffuser decreases the kinetic energy of the air entering the engine. The air enters the diffuser at 127 kPa and 27°C with a velocity of 571 m/s and leaves at 241 kPa and 79°C. The heat lost from the diffuser is estimated to be 1 kJ/kg. Determine the exit velocity in m/s to 1 decimal place. Take the specific heat at constant pressure of air to be 1.009 kJ/(kgK).
