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)?
