Hydrostatic Pressure

Hydrostatic PressureHydrostatic pressure (P), which is applied [or exerted] by a liquid, is proportional to:

  • (i)the depth (or the height) (h) of liquid and
  • (ii)the specific weight of liquid (ε) That is to say: 

That is to say:  P = ε*h

A classic experiment which proves that hydrostatic pressure is proportional to the depth is the following: a container which has 2 holes in different heights is filled with water. The different speed with which the water is ejected from each hole proves that the bigger the depth is the bigger the hydrostatic pressure is.
