Formula, when it applies, and when it does not
Estimate the gauge pressure associated with a liquid density and vertical depth under a simple hydrostatic relationship.
pg = ρgh
When
- Static liquid
- Uniform density
- Standard gravity g = 9.80665 m/s²
Don’t
- This is the static hydrostatic relation for a uniform-density liquid. It excludes flow, gas compression, temperature-dependent density, vessel loads, and any pressure-rating or design decision.
