The Calculated Flow per IDM (highlighted in pink below) is determined by dividing the calculated flow difference (highlighted in blue) by the IDM (found in the pipes grid).
The highlighted fields are defined in the table below:
Field Name |
Definition |
Calc Flow Diff (gpd) |
The downstream manhole calculated flow minus the upstream manhole calculated flow in gallons per day. |
Calc Flow per IDM |
The calculated flow difference divided by the Total IDM. |
