An open vessel contains water upto height 50 cm in it. What is the velocity of efflux through an orifice at height 30 cm above the bottom level ? [Take g = 10 `m//s^(2)`]

Explanation

To find the velocity of efflux through an orifice in an open vessel containing water, we can use Torricelli's theorem, which states that the velocity of efflux \( v \) through an orifice is given by the formula:

\[ v = \sqrt{2gh} \]

where:
- \( g \) is the acceleration due to gravity,
