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 a velocity of 1.2 m/s at the rate of 25 m3/s. If atmospheric pressure head is 10.3 m of water and losses between the inlet and outlet of the draft-tube are negligible, find the length of draft-tube immersed in water. Total length of tube is 5 m.

Please Answer
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 a velocity of 1.2 m/s at the rate
of 25 m3/s. If atmospheric pressure head is 10.3 m of
water and losses between the inlet and outlet of the
draft-tube are negligible, find the length of draft-tube
immersed in water. Total length of tube is 5 m.
