Whenever a static mass of fluid comes into contact with a surface the fluid exerts force upon that surface. The magnitude of this force is known as the hydrostatic force or total pressure force.
The magnitude of hydrostatic force is given by F = ρgh̅A
Where ρ = Density of the fluid, h̅ = Depth of center of gravity of the surface from free liquid surface, A = Area of the surface
Calculation:
Given, h = 10 m
h̅ = 10/2 = 5 m
Area per metre length = 10 × 1 = 10 m2
Force acting on vertical wall = ρ × g × h̅ × A = 1000 × 9.81 × 5 × 10 = 490500 N = 490.5 kNLast updated on Jul 2, 2025
