Consider a cylindrical tank of radius 1m is filled with water. The top surface of water is at 15 m from the bottom of the cylinder. There is a hole on the wall of cylinder at a height of 5m from the bottom. A force of 5 x 10 5 N is applied an the top surface of water using a piston. The speed of efflux from the hole will be: (given atmospheric pressure P A = 1.01 x 10 5 Pa, density of water 
= 1000 kg/m 3 and gravitational acceleration g = 10 m/s 2 )
