EPANETCURVES

The command EPANETCURVES creates and edits EPANET Curves

To use, call EPANETCURVES from the command line, menu, toolbar or Ribbon and choose the style you want to edit:

On this screen you can:

• New - Create a new curve
• Delete - Delete selected curves if not in use
• Edit - Edit the selected curve
• Copy - Copy and edit the selected curve
• Pick - select on the screen an item that has the curve you want to edit

When clicking the button New, you will be asked to choose the type of curve:

There are 4 types of curves in EPANET:

1. Volume Curve - describes the variation of volume as a function of height of storage of EPANET Tank (raised reservoir)
2. Efficiency Curve - describes the efficiency variation of the pump as a function of the flow seeping into EPANET Pump
3. Pump Curve - describes the pump load variation as a function of flow seeping into EPANET Pump
4. Head Loss Curve - describes the valve head loss variation as a function of flow seeping into EPANET Valve

After choosing the type of curve, click the OK button and the following screen is shown:

1. Give a name to the curve in the properties frame on the left side at the top
   Note, EPANET is very sensitive with object naming. Do not use special characters. Spaces will be converted to "_" in the INP file generated by the command EPANETEXPORT and the name must be limited to 31 characters
2. In the table on the left, enter the values to create the curve. Note that you can change the column order, but the graph will be the same.
3. Depending on the type of curve, the graph will behave in one way. It may also be that the data reported in the table generate invalid curves. In this case, the Priority property will appear with the icon
