For the consumption of 430 kg of petrol

a flying bomb had a range of 260 km, an average speed of 174 m/s & thrust of 2678 N. Assuming the CV of the fuel 42676 KJ/Kg, maximum temperature rise in the combustion chamber as 820ÂșC, the diameter of the discharge nozzle as 0.304 m, the altitude of the flight as 606 m, & CP of the exhaust gases as 1.05 kJ/kgK,

Calculate.

a) Fuel - air ratio.

b) Approximate temperature of the exhaust gases & their relative velocity to the bomb.

c) Propulsive & overall efficiency of the unit.
