modelPressureDropsParallel
Test with multiple resistances in parallel
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model tests two resistances in parallel.
The flow path at the bottom of the model also has one additional hydraulic diameter
model, but it has noRes.disableComputeFlowResistance=true, thereby
removing the calculation of the flow resistance in that model.
