Water Well Pump — Flow Rate & Lift Modeler

Model a submersible well pump's flow and lift: required flow rate, static water level, drawdown, total lift head, pipe friction loss, and efficiency — then get total dynamic head (TDH), required hydraulic horsepower, and a recommended pump discharge sizing.

OFFDemand & Flow

Required GPM cross-checked against typical fixture & usage demand.

OFFStatic Water Level

Depth to water with the well at rest.

OFFDrawdown

Water level drop while pumping vs. safe pump setting.

OFFPipe Friction

Head loss vs. pipe length and velocity limits.

OFFEfficiency

Plausible pump/motor efficiency for the duty point.

OFFDischarge Sizing

Recommended discharge pipe & horsepower at TDH.
