A cylinder of height 20 m 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
20
25.5
10
5
Answer
Use Bernoulli's theorem just inside and outside the hole
Pinside + ρgh + 0 = Poutside + (ρV2)/2
ρ x 10 x 20 = ρ x V2/2
V2 = 400
V = 20
The correct option is A.

Step-by-step explanation:
p×10×20=p×V2/2
V2=400
V=20
