Hydrostatic Pressure on Submerged Surfaces

Hydrostatic pressure creates force on submerged plane surfaces. The force depends on the fluid pressure and the area of the surface. The way that force acts changes with the surface position.

For a horizontal surface, the depth stays the same across the whole area. That means the pressure is unif...

Consider plane surfaces submerged in a fluid with a specific weight. Forces are developed on the surfaces because of the fluid.

The resultant of the forces developed on the horizontal surface is given by the product of pressure exerted by the fluid on the surface and the area of the surface acting through the centroid of the area.
