Well Pump TDH Sizer
iOS Universel / Utilitaires
Drilling a new well and need to pick the right pump horsepower? Undersized pumps cannot deliver enough pressure uphill. Oversized pumps waste electricity and burn out faster. This calculator computes total dynamic head and recommends the correct submersible pump HP for your well.
Enter well depth, static water level, drawdown, pipe length, pipe diameter, flow rate in GPM, and discharge pressure. Get pumping water level, friction loss (Hazen-Williams), pressure head, total dynamic head (TDH), calculated HP, and recommended standard motor HP.
WHAT IT CALCULATES:
- Pumping water level (static + drawdown)
- Pipe friction loss using Hazen-Williams formula
- Pressure head from discharge PSI
- Total Dynamic Head (TDH) in feet
- Required horsepower at 60% efficiency
- Nearest standard motor HP recommendation
PIPE SIZES:
- 1 inch through 4 inch Schedule 40
- Actual internal diameter for accurate friction loss
KEY FEATURES:
- Hazen-Williams friction loss calculation
- Standard HP recommendations (0.5 to 10 HP)
- Works completely offline
- No account or login required
Built for well drillers, pump installers, plumbers, and rural homeowners.
