What do you mean by pressure of a liquid? Write its Sl unit.

Explanation:

The pressure of a liquid is the rate of the force applied by the liquid on a surface per unit area of the surface.

i.e P =

where P is the pressure, F is the force and A is the area.

The depth of the liquid determines its pressure at a definite lower point. As the pressure of a liquid at the bottom of a its container is greater than the pressure at the top of the liquid.

Thus,

P = σhg

where P is the pressure, σ is the density of the liquid, h is the height and g is the force of gravity.

It is measured in Pascals or N.

The pressure of liquid has a lot of applications, viz: siphon, force pump, lift pump etc.
