Pressure in case of liquid

If you dive below the water the height of water above you also puts pressure on you.

At a depth of 10m of water the pressure has increased by 100 K Pa (1bar) and for each further 10m of depth the pressure increases by another 100 k Pa.

The increase in pressure below the surface of liquid depends on

  1. The depth below the surface (h)
  2. The density of the liquid (d)
  3. The gravitational field strength ( g = 10 m / s2).

It does not depend on anything else.

The pressure below the surface of a fluid is given as:

Pressure = (Density) X (Height) X (Gravitiational field strength)

P=d X g X h = dgh
