Fluid Statics
Hydrostatic Pressure Simulator
Analyze the pressure exerted by a static fluid at varying depths. Explore liquid densities, gauge vs. absolute scaling, and compute the resultant lateral hydrostatic force exerted on channel walls.
Gravity (g)
9.81 m/s²
Standard Earth gravity
Fluid density
1000 kg/m³
Water
Bottom Pressure
98.1 kPa
At maximum depth
Parameters
Fluid Preset
Depth sensor sweep
Fluids Equations
Hydrostatic Pressure
P = ρ * g * h
Hydrostatic Wall Force
F = 1/2 * ρ * g * h²
Gage to Atmospheres
P_atm = P / 101,325 Pa
Hydrostatic pressure increases linearly with depth, forming a triangular force distribution on retaining walls.
This calculation assumes static fluid conditions and ignores atmospheric pressure (gage pressure only).
