Calculate the velocity with which a liquid emerges from a small hole in the side of a tank of large cross-sectional area if the hole is 0.2 m below the surface liquid (g = 10 `"ms"^(-2)`.

Text Solution

Verified by Experts

From Torricelli theorem, velocity of efflux `upsilon=sqrt(2gh)`
`=sqrt(2xx10xx0.2)`
=2m/s
