A cylindrical vessel of uniform cross-section contains liquid upto the height' H’ . At a depth `H = H/2` below the free surface of the liquid there is an orifice. Using Bernoulli's theorem, find the velocity of efflux of liquid.

Two vessels A and B of cross sections as shown contain a liquid up to the same height. As the temperature rises, the liquid pressure at the bottom (neglecting expansion of the vessels ) will :

A cylindrical vessel of cross section A contains water to a height h. There is a hole in the bottom of radius 'a'. The time in which it will be emptied is:

A liquid is filled in a vessel and a hole is made at a depth h below the free surface of the liquid. Statement-1 : Greater is the distance of the hole form the free surface of liquid, greater will be the velocity of efflux. And Statement-2 The speed of the liquid coming out of the orifice depends on the quantity of liquid in the vessel.

A beaker containing a liquid of density rho moves up with an acceleration a . The pressure due to the liquid at a depth h below the free surface of the liquid is.

A liquid of density rho is filled in a vessel up to height H and a hole of cross section area A is made at a depth h below the free surface of liquid. The speed of liquid coming out of the hole is independent of

A wide tank of cross-section area A, containing a liquid to a height H, has an orifice at its base of area A/3 . The initial velocity of top surface of liquid is

A cylindrical vessel of radius r is filled with a homogeneous liquid upto a height h. It is found that the force exerted by the liquid column on the bottom of the cylinder is equal to the force exerted by the liquid on the sides of the cylinder. What is the relation between r and h?

A cylindrical vessel of area of cross section A is filled with a liquid up to a height H . A very small hole of area of cross section a is made at the bottom of the vellel. Find the time taken by the vessel to become empty.

The pressure at depth h below the surface of a liquid of density rho open to the atmosphere is
