A water tank has a hole at a distance `x` m from free water surface. If the radius of the hole is 2 mm and velocity of efflux of water is `11 m//s.` Find V. `(g = 9.8 m//s^2)`

In a vessel containing water, a hole is made at a depth of 0.10 m from the free surface. What would be the velocity of efflux ?

There is a small hole of diameter 2 mm in the wall of a water tank at a depth of 10 m below free water surface. Then the velocity of efflux of water from the hole will be

A body is released from the top of a tower of height 50 m. Find the velocity with which the body hits the ground. (g=9.8 m/s^2)

Water flows through a tube as shown in the given figure. Find the difference in mercury level, if the speed of flow of water at point A is 2 m//s and at point B is 5 m//s . ( g=9.8m//s^2 )
