Question
There is a hole of area 
in the bottom of a cylindrical vessel containing fluid up to height h. The liquid flows out in time t. If the liquid were filled in the vessel up to height 4 h, then it would flow out in time
- t
- 2 t
- 4 t
The correct answer is: 2 t
When h is quadrupled, t is doubled

A large open tank has two small holes in its vertical wall as shown in figure. One is a square hole of side ‘L’ at a depth ‘4y’ from the top and the other is a circular hole of radius 'R' at a depth 'y’ from the top. When the tank is completely filled with water, the quantities of water flowing out per second from both holes are the same. Then, ‘R’ is equal to:
