We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Yes, the fluid is incompressible. I do understand that comparing a 2D system to experimental data might not be precise, but I don't understand why well pump manufactures advertise with pumps with either a large head or a large flow. Because two different pumps can operate on the same flowrate, while one can produce a larger head then the other.

Maybe I need to rephrase my question then to "Is it possible to compare two pumps in Ansys with the same flow rate but with a different head?" 

Do I have to change the outlet pressure or is only one solution possible (when connecting two different pumps with the same flow rate to the same jet-inlet)?
