Pump as a Node In Water and System Head Curve
System Head Curve Note: This is a feature often asked for in InfoSWMM and SWMM5. Pumps are links in the SWMM5 engine. The dialog box for system head curve is shown below. Click here for the methodology of system head curve. Input for system head curve: • Flow Unit – Select the desired flow unit. • Head Loss Equation – Select from Manning, Darcy-Weisbach (Colebrook-White), or Hazen–Williams formula. • Pipe 1 – The pipe that connects the upstream reservoir with the pump (i.e., pipe on the suction side of the pump). • Pipe 2 – The pipe that connects the pump with the downstream reservoir (i.e., pipe on the discharge side of the pump). • Coefficient – Roughness coefficient. • Head at Position 1 – Head at the upstream reservoir. • Head at Position 2 – Head at the downstream reservoir. • Length – Length of the pipe (i.e., pipe 1 or pipe 2). • ...
