Question

# A large open tank has two holes in the wall. One is a square hole of side L at a depth h from the top and the other is a circular hole of radius R at a depth 4h from the top, When the tank is completely filled with water, quantities of water flowing out per second from both holes are the same. Then R is equal to

Solution

## The correct option is A L√2πSince the water quantity from both the holes are equal, we havea1v1=a2v2⇒L2√2gy=πR2√2g(4y)∵ velocity of efflux at depth h is given by v=√2gh⇒R=L√2π
