Find the time required for a cylindrical tank of radius 2.5 m and height 3 m to empty through a round hole of radius 2.5 cm with a velocity `2. 5sqrt(h)` m/s, `h` being the depth of the water in the tank.

Find the time required for a cylindrical tank of radius r and height H to empty through a round hole of area a at the bottom. The flow through the hole is according to the law v(t)=ksqrt(2gh(t)) , where v(t) and h(t) , are respectively, the velocity of flow through the hole and the height of the water level above the hole at time t , and g is the acceleration due to gravity.
