Question: The following data pertain to a turbojet flying at an altitude of 9500m

Speed of the turbojet = 800 km/hr

Propulsive efficiency = 55%

Overall efficiency of turbine plant = 17%

Density of air at 9500 m altitude = 0.17 kg/m3.

Drag on the plane = 6100 N

Assuming CV of fuel used as 46000 kJ/kg,

Calculate :

i) Absolute velocity of jet.

ii) Volume of air compressed per minute.

iii) Diameter of jet.

iv)Power output of unit.

Subject : Thermal and Fluid Power Engineering
