Consider a cylindrical tank of radius 
is filled with water. The top surface of water is at 
from the bottom of the cylinder. There is a hole on the wall of cylinder at a height of 
from the bottom. A force of 
is applied an the top surface of water using a piston. The speed of efflux from the hole will be: (given atmospheric pressure 
, density of water 
and gravitational acceleration 
)
