Information
In the fifth step, the mass flow rate sink is split into a massFlowRate component and a free sink.
The Sink_free model is locally underdetermined by one equation (it lacks the definition of the mass flow rate), which is indicated by a minus sign.
The MassFlowRate model is overdetermined by one equation, which is indicated by a plus sign.
Combining both models yields a balanced model. See also UsersGuide.BalancedModels.
The position of the massFlowRate component within the loop is arbitrary.
Further documentation is available in the ClausiusRankine package.
