modelPumpParallel
Example that tests the model pump parallels
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This example demonstrates the use of the flow model with two different configurations. At steady-state, all flow models have the same mass flow rate and pressure difference.
