Hydrostatic Paradox

We will take three vessels A, B and C of different shapes which are open both at the top and the bottom ends. These vessels are connected with a common pipe at the bottom.

Now, we will fill the three vessels with the same liquid. The reading, we note that pressure will be same even through the quantity of liquid in different vessel is different.

It means that the liquid pressure at a point is independent of the quantity of the liquid but depends upon the depth of point below the liquid surface.

This is known as “Hydrostatic Paradox”.

Hydrostatic Paradox

Hence, the pressure exerted by a liquid depends only on the height of the fluid column and is independent of the shape of the containing vessel.
