Pump Sizing & System Curve Analyzer
Estimate total dynamic head and power, then compare a user-supplied pump curve at the design duty.
Engineering use case
For a chilled-water pump at 10 L/s, 12 m static head and 6 m estimated losses, review TDH and power before comparing a sourced manufacturer curve.
Method & limitations
Method: system curve H = static head + KQ², TDH, ρgQH, and efficiency-adjusted input power. Results are preliminary estimates and exclude vendor-specific selection, NPSH and control behavior.
Formulas, source and scope

FAQ
Does the tool invent a pump curve?
No. Hydraulic power and TDH are calculated from your heads and flow. An operating point exists only after you supply a curve. g = 9.80665 m/s² in the engine.
What is the on-page duty?
Defaults are 0.01 m³/s, 12 m static head, 4 m pipe loss and 2 m local loss. Review TDH and power, then compare a sourced manufacturer curve.
