System Head Curve with intermediate high point

Problem

How can I view the static head of a pump, especially when there's an intermediate high point that may see part-full flow?

 

Solution

First, ensure that you have an air valve node element at the high point(s) that you expect to see part full flow, and ensure that the "Treat as junction?" property is set to "false". Next, turn the pump(s) off and compute a steady state simulation. The pump head (or the
difference in upstream/downstream HGL) should be the static head. You can also right click on the pump and choose "system head curve", then look at the zero flow point.
