Velocity Efflux | MCQs

Explanation

Torricelli's theorem is specifically used to find the velocity of efflux.

It states that the velocity of fluid flowing out of an opening (such as a small hole in a container) can be found using the equation:

v=  under root 2gh

where:

 𝑣 is the velocity of efflux,

𝑔  is the acceleration due to gravity (approximately 9.81 m/s²),

ℎ  is the height of the fluid above the opening.

This theorem is particularly useful in situations involving the flow of liquids through openings or nozzles.
