A vessel completely filled with water has holes 'A' and 'B' at depths 'h' and '3h' from the top respectively. Hole 'A' is a square of side 'L' and 'B' is circle of radius 'r'. The water flowing out per second from both the holes is same. Then 'L' is equal to

A

`r ^(1/2) (pi)^(1/2) (3)^(1/2)`

B

`r (pi) ^(1/4) (3)^(1/4)`
