Hydraulic Water Well Engineering

Submersible Well Pump & Head (TDH) Sizer

Calculate pumping Total Dynamic Head (TDH), static water level lift, friction loss in drop pipe, 40/60 PSI service pressure head, and 230V submersible motor horsepower (HP).

Pumping Head & Motor Recommendation

Total Dynamic Head (TDH)

Lift + Elevation + Pressure + Pipe Friction

356 Ft Head

Submersible Motor Rating (HP)

230V 2-wire or 3-wire deep well unit

1.5 HP Motor

Pressure Tank Size (Drawdown)

Minimum 1-minute pump cycle runtime

44-Gallon Tank

1 PSI equals 2.31 feet of vertical water column head. Sizing a pressure tank to guarantee at least 60 seconds of continuous pump run prevents short-cycling motor burnout.
