Hydrostatic Pressure Calculator
Calculate fluid pressure at depth, gauge or absolute pressure, force on a bottom or vertical wall, and U-tube balance for common liquids.
Pressure at depth
Hydrostatic pressure is the pressure caused by a stationary column of fluid. It rises linearly with fluid density, local gravity and depth.
p is gauge pressure, rho fluid density, g local gravity and h depth below the surface.
Absolute pressure adds atmospheric or surface pressure to the fluid column.
