Hi
I am new to WaterGems and have two questions.
first, when I want to model a water network do I need to assign appurtenances elevation or their top ground elevations?
I mean if I am modeling a valve I should indicate its elevation or ground elevation above the valve.
second, how can I model the vertical bend in watergems, and pipe slope is important in modeling or not?
please see the following capture.
Hamid, Yes, you should assign appurtenances elevations because the elevations you enter help to determine the correct pressure at that location once the model is computed. When you assign the elevation assign it the actual elevation of the valve, not the ground elevation above the valve. It might be useful to you to know that we define the elevation of junctions, valves, and pumps as the elevation at the centroid for these elements. Bends are modeled as minor losses in WaterGEMS. Adding an actual bend to a pipe doesn't do anything for the hydraulics of the model. The following wiki shows how you can add minor losses through the engineering library. communities.bentley.com/.../22947.will-the-minor-losses-associated-with-pipe-bends-be-automatically-accounted-for.
