Question 208: Properties of Matter

Question

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

Accepted Answer

The velocity of efflux of water is given $$v = \sqrt {2gh} $$
Here $$h$$ is the height of the free surface of water from the hole
$$	herefore$$ $$v = \sqrt {2 	imes 10 	imes 20}  = 20m/s$$
