Hydrostatic gauge pressure
Estimate pressure increase below the surface of a stationary fluid.
Method and scope
p = ρgh using standard gravity.
Use hydrostatic gauge pressure for educational calculation or a clearly scoped arithmetic estimate. Intended for Learners, General educational use.
Inputs- Fluid density — kg/m³, g/cm³, g/mL
- Vertical depth — m, cm, ft
SOURCE AND LIMITS
- OpenStax, College Physics 2e, §12.2 Bernoulli’s Equation; static-fluid pressure increase Δp = ρgh. ↗
Assumptions: The fluid is stationary and density is uniform. Depth is measured vertically below the free surface. The answer is gauge pressure, not absolute pressure.
Limitations: Actual pressure depends on local gravity, fluid layering, and density variation.
