The mean pressure on the walls of a vessel containing liquid upto height h is______

The force on the walls of a vessel of a contained gas is due to

Prove that the average pressure of a liquid (density p) on the walls of the container filled upto height h with liquid is 1/2 h rhog .

There is a small hole in the bottom of a fixed container containing a liquid upto height 'h' . The top of the liquid as well as the hole at the bottom are exposed to atmosphere. As the liquid come out of the hole. (Area of the hole is 'a' and that of the top surface is 'A' ) :

There is a hole of area (1)/(25)cm^(2) in the bottom of a cylindrical vessel containing fluid up to height h . The liquid flows out in time t . If the liquid were filled in the vessel up to height 4h , then it would flow out in time

The shape of the vessel containing the liquid does not affect the pressure. This is known as

Three vessels containing same liquid, upto the same height h, then pressure at the bottom is ( A_1 > A_2 > A_3 )

Give reason for the following : (a) Gases fill up completely the vessel in which they are kept. (b) Gases exert pressure on the walls of the containing vessel.
