Hydrostatic Pressure Calculator

Science & Engineering

P = ρgh · dams, diving, tanks

Quick Answer

Hydrostatic Pressure Calculator: P = ρgh · dams, diving, tanks. Hydrostatic Pressure Calculator uses standard science & engineering formulas to compute accurate results instantly.

How it works

  1. 1P=ρgh — independent of container shape
  2. 2Water adds ~98 kPa (≈1 atm) per 10 m of depth
  3. 3Just enter fluid density and depth
  4. 4For diving, add surface pressure 101.3 kPa on top

Fluid & depth

kg/m³
m
Hydrostatic pressure98.07kPa
Equivalent：0.098 MPa · 0.97 atm
Absolute (diving)：199.4 kPa
Pressure depends only on depth and density — hence communicating vessels, dam profiles and siphons. At 30 m recreational depth absolute pressure is ~4 atm: air consumption rises sharply and no-deco limits apply. Fresh vs seawater buoyancy differs ~2.5% — adjust weights. Dam walls see a triangular load, thickest at the base where P=ρgh governs the design.
