A conical draft tube having diameter at the top as 2.0 m

and pressure head at 7 m of water (vacuum) discharges water at the outlet with the velocity of 1.2 m/s at the rate of 25 $m^3$/s. It the atmospheric pressure head is 10.3 m of water & losses between inlet & outlet of the draft tubes are negligible find the length of the draft tube immersed in water total length of the tube is 5 m
