Water is filled in a cylindrical container to a height of 3m. The ratio of the cross-sectional area of the orifice and the beaker is 0.1. The square of the speed of the liquid coming out from the orifice is (g = 10 m/s 2 )
Text Solution
Verified by ExpertsThe correct answer is:
A
Let A = cross-section of tank
a = cross-section hole
V = velocity with which level decreases
v = velocity of efflux
From equation of continuity 
By using Bernoulli's theorem for energy per unit volume
Energy per unit volume at point A
= Energy per unit volume at point B
