Liquid Pressure

Test yourself

Liquid Pressure

As you dive deeper into a swimming pool, there is more water (and weight) on top of you. This extra weight exerts a larger force (and higher pressure) on your body. The deeper down you swim, the more pressure you feel.

Illustrative background for Liquid pressure = density x gravitational field strength x depthIllustrative background for Liquid pressure = density x gravitational field strength x depth ?? "content

Liquid pressure = density x gravitational field strength x depth

  • The pressure beneath a liquid’s surface = density of fluid x gravitational field strength x depth.
  • Pressure is measured in pascals (Pa).
  • Density of fluid is measured in g/cm3.
  • Depth is also equal to the height of the column of water above you.
