I have multiple variable speed pumps in parallel, but some of them have different pump curves. This is the way they are in the field. How do you model that?Area: Modeling, Problem ID#: 89805
Because of the constraints for VSPs there are only two options:1) If the pump curves are close enough to each other then you can approximate an "average" pump curve for all the pumps so you model them in parallel as VSP's.2) Model the pumps that have the same pump curve as VSP's and then model the other pumps that don't have the same pump curves as regular pumps that have all the necessary controls on them to make them act like VSP's.
For more information on parallel variable speed pumps, please see the Help topic in WaterGEMS or WaterCAD called "Parallel VSPs".
