In a jet engine a diffuser decreases the kinetic energy of the air entering the engine. The air enters a the diffuser at 98 kPa and 25C with a velocity of 437 m/s and leaves at 238 kPa and 74C. The heat lost from the diffuser is estimated to be 3 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).
