In a turbo-jet engine the momentum of the gases leaving the nozzle produces the propulsive force. The enthalpy and velocity of the gases at the nozzle entrance are 1200 KJ/Kg and 200 m/s respectively. The enthalpy of the gas at exit is 900 KJ/Kg. If the diameter of the nozzle at exit is 500 mm and the gas density at the nozzle inlet and exit are 0.81 kg/m3and 0.39 kg/m3 respectively. Determine the diameter of the nozzle at inlet. 4.

Question

In a turbo-jet engine the momentum of the gases leaving the nozzle
produces the propulsive force. The enthalpy and velocity of the gases at
the nozzle entrance are 1200 KJ/Kg and 200 m/s respectively. The
enthalpy of the gas at exit is 900 KJ/Kg. If the diameter of the nozzle at exit
is 500 mm and the gas density at the nozzle inlet and exit are 0.81 kg/m3
and
0.39 kg/m3
respectively. Determine the diameter of the nozzle at inlet.
