How to Evaluate Bottom Force on Plate?

Bottom Force on Plate evaluator uses Bottom Force = Density of Fluid*[g]*(Distance of Top Edge from Free Surface+Vertical Distance of Point from Free Surface)*Area of Surface to evaluate the Bottom Force, The Bottom Force on Plate formula is defined as the function of the density of the fluid, gravitational acceleration, the distance of the top edge from the free surface, the Vertical Distance of the Point from the Free Surface, and the Area of the Surface. It is a common experience that an object feels lighter and weighs less in a liquid than it does in air. This can be demonstrated easily by weighing a heavy object in water with a waterproof spring scale. Also, objects made of wood or other light materials float on water. These and other observations suggest that a fluid exerts an upward force on a body immersed in it. This force that tends to lift the body is called the buoyant force. The buoyant force is caused by the increase of pressure with depth in a fluid. Bottom Force is denoted by FBottom symbol.
