The following data pertains to a turbo-jet system flying at 9500 m height with a speed of 800 km/hr and propulsive n=55%. Taking the following data: P(density of air at 9500 m height) = 0.17 kg/m', Drag on the plane= 6.1 kN, Calorific value of fuel used = 46 MJ/kg. Find out the following: (i) Absolute velocity of the jet, (ii) Mass of air compressed/min, (iii) Diameter of the jet, (iv) Power output of the turbine unit kW and (v) air-fuel ratio used.
