How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.

Diagnose
This tool does not attach diagnose observations.
Assumptions
- Uniform density. Same relation as tank hydrostatic pressure, signed for profiles.
Provenance
- Hydrostatics along a pipeline profile. Positive Δz is an increase in elevation.
