How to use this data
h[m]=Δp[Pa]/(ρg). Store head in canonical mm; pressure in kPa. 1bar=100kPa; psi display uses exact customary-unit definitions.
CHECK THE METHOD
Worked example
100 kPa at 1000 kg/m³ gives 10.19716 m liquid head. At lower density the same pressure requires more head.

Common lookup questions
What should I confirm before using this lookup?
Hydrostatic pressure head is one term in TDH. It is not total pump duty, gauge datum, available NPSH or a pressure-rating check; confirm liquid density and boundary pressures.
