Question

The velocity of efflux of a liquid for a small height of water column in a tank, through an orifice at the bottom of the tank does not depend on:

• A. density of liquid
• B. height of the liquid column above the orifice
• C. acceleration due to gravity
• D. none of the above

Answer 1

The correct option is A density of liquid

We know that velocity of efflux is given by $v=\sqrt{2gh}$, which is independent of the density of the liquid.
