To add a minor loss collection to a pressure pipe:

1. Click a pressure pipe in your model to display the Property Editor, or right-click a pressure pipe and select Properties from the shortcut menu.
2. In the Physical: Minor Losses section of the Property Editor, click the Ellipses (...) button next to the Minor Loss Coefficient field.

The minor loss type and its associated headloss coefficient appears in the table in the Minor Loss Collection dialog box. Note that the Headloss Coefficient column in the table is not editable. You can edit the values of a minor loss type in the Engineering Libraries in the Editor pane.
7. When you are finished adding minor losses to the table, click Close. The composite minor loss coefficient for the minor loss collection appears in the Property Editor.
