A tank with a small circular hole contains oil on top of water. It is immersed in a large tank of the same oil. Water flows through the hole. The ratio of the cross sectional area of tank to that of hole is 50. The density of oil is 800 Kg/m^3. Find

1)The velocity of water flow

2)When the flow stops, the position of the oil water interface in the tank?

3)The time at which the flow stop

2. Relevant equations

3. The attempt at a solution

I got the first 2 answers as 6.3m/s and height of water left = 8m respectively

I tried to solve last and got 16 s (app.) but that is wrong.

The answer is 32 s
