Liquid pressure

The pressure exerted by a liquid per unit area of the surface in its contact is called liquid
pressure.

▪ Formula to calculate liquid pressure is ,

Liquid pressure(P) = Height of liquid(h)x Density of liquid(d)x Accel. due to gravity (g)
▪ i.e. P = hdg

▪ Factors affecting liquid pressure are;

i. Height of liquid(h)

ii. Density of liquid (d)

iii. Acceleration due to gravity (g)

Properties of liquid pressure;

• Liquid applies pressure in all directions.

• Liquid pressure increases with depth.

• Liquid pressure does not depend upon the shape of the vessel.

• Liquid pressure depends on density of liquid.
