Hydrostatic pressure and force on a wall

Change the depth and the liquid to see the triangular pressure diagram on a wall, the total force on it and where that force acts.

Works in metric or imperial units.

Questions students ask

What is the hydrostatic force on a vertical wall?

F = ½ρgh²b per wall of width b, acting at h/3 above the base.

Does the size of the reservoir matter?

No. Only the depth of the liquid, its density and the width of the wall.
