Fluid statics:Pressure at a point

Pressure at a point

Determine the total force on a wall of an open tank 2m wide containing fuel oil of density 924 kgm-3 at a depth of2 m.

Fluidstatic-0033

Solution

To determine the pressure at a point in the static liquid below the free surface, consider the equilibrium forces on a wedge-shaped element of the liquid.
