Figure here shows the vertical cross-section of a vessel filled with a liquid of density `rho`. The normal thrust per unit area on the walls vessel at point. `P`, as shown, will be

In the adjacent figure a cylindrical vessel of mass M and cross - sectional area A is placed inverted on a fixed smooth piston of same cross - sectional area fixed to the ground . The space between the cylinder and priston is completely filled with liquid of density rho . There is a small office of cross - sectional area a ( a lt lt A) at the top top portion of this vessel . ( intially length of the liquid column in the vessel is H ) Speed of the liquid with which it comes out of the vessel is

The space between the cylinder and priston is completely filled with liquid of density rho . There is a small office of cross - sectional area a ( a lt lt A) at the top top portion of this vessel . ( intially length of the liquid column in the vessel is H ).Find the speed of the vessel with which it move

The force F needed to support the liquid of density rho and the vessel on it, in figure, is

A block of mass m and density p is hanging from a string . If it is lowered into a vessel of cross-sectional area A containing a liquid of density sigma(lt rho) and gets fully immered, the increase in pressure at the bottom of vessel would be

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.
