Pressure Pipe-Physical
Pressure Pipe-Physical Attributes
| Attribute | Description |
|---|---|
| Is Virtual? | If True, the physical properties will be ignored, except when using the Gradually Varied Flow (GVF) solver. Can be used to connect pumps to nodes without accounting for hydraulic properties. |
| Diameter | The diameter of the cross section of the currently highlighted element. |
| Material | The name of the material used. Alternatively, clicking the ellipsis button opens the Material Engineering Library, allowing you to select a pre-defined material. If a pre-defined material is chosen, the roughness value will change accordingly. |
| Manning’s n | The Manning’s roughness of the currently highlighted element. This field is available only if you selected Mannings as the default Pressure Friction Method in the Calculation Options Manager. |
| Hazen-Williams C | The Hazen-Williams roughness of the currently highlighted element. This field is available only if you selected Hazen-Williams as the default Pressure Friction Method in the Calculation Options Manager. |
| Darcy-Weisbach e | The Darcy-Weisbach roughness of the currently highlighted element. This field is available only if you selected Darcy-Weisbach as the default Pressure Friction Method in the Calculation Options Manager. |
| Kutter’s n | The Kutter’s roughness of the currently highlighted element. This field is available only if you selected Kutters as the default Pressure Friction Method in the Calculation Options Manager. |
| Elevation (Start Invert) | The start, or upstream, invert of the currently highlighted element. |
| Set Invert to Start Node? | Sets the start invert of the current element to the elevation of the start node (upstream). Set this to False to enter a value for the elevation of the invert, or set this field to True to use the start-node elevation. |
| Elevation (Stop Invert) | The stop, or downstream, invert of the currently highlighted element. |
| Slope | The slope. |
