EPANET - Efficiency Curve

An efficiency curve determines the efficiency of pump (Y in percent) as a function of pump flow rate (X in flow units)

This curve has the following properties:

• Identification
  • Description (Description, String) - Use a user-friendly description when the item name is not sufficient
  • Name (Name, String) - item name
    Avoid names that are too long or contain the following characters: '*', '>', '<', '/', '\', '"', ':', ';', '|', '=', '`', '#', ',', '?'
• Object
  • Priority (Priority, Enum) - Information regarding the item's current status. Can be:
    • Neutral: no issues
    • Critical: A problem preventing the calculation or use of the item
  • Error Evaluation (CurveError, Enum) Result of the data evaluation
  • Curve Data (CurveData, IListClonavel) - the curve data, with the columns:
    • Flow Rate (X, Double) - the flowing rate
    • Efficiency (Y, Double) - the efficiency to be considered

The data are entered into the table and plotted on the graph for better visualization:

The efficiency must represent the run-of-river efficiency, which takes into account the mechanical losses in the pump itself, as well as electrical losses in the pump motor. The curve is only used for energy calculations. If not provided, the overall pump efficiency (a single number) in the project's power options is used instead
