Questions  

A cylinder of height 20m is completely filled with water. The velocity of efflux of water (in ms-1) through a small hole on the side wall of the cylinder near its bottom is

a
10 ms-1
b
20  ms-1
c
25.5  ms-1
d
5  ms-1

detailed solution

Correct option is B

Just inside and outside of the hole, applying Bernoulli's theorem,

Pinside+ρgh+0=poutside+ρV22

ρ×10×20=ρ×v22v2=400v=20

Hence the correct answer is 20m/s.
