Method
Total dynamic head = static elevation + required pressure head + straight-pipe loss + fitting loss. Water friction uses entered Hazen-Williams C and actual internal diameter.
Important limits
Use the pump curve at the calculated duty point. This does not verify NPSH, bore yield, transient pressure, pipe rating or pump suitability.
Technical reference
Estimate pump total dynamic head from static lift, pressure requirement, pipe friction and fitting losses.
What to enter
Use current, project-specific values for static lift, pressure requirement, pipe friction and fitting losses. Check every unit before calculating and compare like-for-like inputs. The template controls the actual fields and calculations; this supporting copy does not replace its labels, formulas or result logic.
How to use the result
Use total dynamic head as a planning estimate. Pump curve, source level, pipe details, fittings and operating point must be verified for final selection.
Before making a decision
Verify source measurements, equipment specifications and operating conditions. Have a qualified professional review the final selection, safety and installation requirements before purchase, connection or construction.
