The figure below shows a tank of diameter D = 1.8 m containing water of height H = 5.8 m with a small hole of diameter d = 4.9 cm at the bottom of the tank. Assuming the flow to be incompressible and inviscid, estimate the time I taken for the water level in the tank to drop to a height of 3.3 m. Assume the flow to be quasi-steady, such that the horizontal water level falls at a much slower rate compared to the water velocity leaving the hole. The gravitational acceleration g is 9.81 m/s.
