Inference Rules - Pump and Pumping Station Parameters
Missing network parameters can be inferred from existing data, allowing you to fill in gaps in your data with reasonable values.
Inference data is edited on the Inference Data Editor.
Inference is applied to the current selection on the GeoPlan. If there are no objects selected, you will be given the option to carry out inference on the entire network or to Cancel.
The following parameters can be inferred for pumps:
| Pump Parameter | Inferred from |
|---|---|
|
Nominal Flow |
Mid-range of the flow values in the Pump Curve. The nominal flow is calculated from values in the Flow/ Head/Power table on the Pump Curve Page: Sum of flows / Number of entries in table |
|
Nominal Speed |
Speed entered in the parameters section of the Inference Rule. |
|
Maximum Speed |
Nominal Speed of the pump. If the Nominal Speed of the pump is not available, the speed entered in the parameters section of the Inference Rule is used. |
The following parameters can be inferred for Pumping Stations:
| Pumping Station Parameter | Inferred from |
|---|---|
|
Duty Head |
The highest rated head of all the pumps in the station calculated from the affinity law:
where: H = Head n = Rotational speed of impeller "o" indicates rated value |
