Extends from Modelica.Icons.Example.

Information

Checks enforcePressureDrop:

If enforcePressureDrop = true, the product of mass flow rate and pressure drop m_flow*dp >= 0 is enforced, independent of the setpoint. If pressure clipping becomes active, this is indicated by a red circle in the icon layer.
If enforcePressureDrop = false, the pressure drop may violate the second law of thermodynamics. In this case, a warning is issued and the condition is indicated in the icon layer.

For inverse calculations, it may be advantageous to set enforcePressureDrop = false, as this simplifies the equation system.
