FCSys.Conditions.Adapters.AmagatDalton

Adapter between the Amagat and Dalton connectors

Information

This model is used to convert the representation of mixtures between Amagat's law of partial volumes and Dalton's law of partial pressures.

For more information, please see the documentation in the Connectors package.

Extends from FCSys.Icons.Names.Top1.

FCSys.Conditions.Adapters.ChemicalReaction

Adapter between the Chemical and Reaction connectors

Information

This model is used to add the stoichiometrically-weighted chemical potential of a species to the net chemical potential of a reaction. The species is produced at the stoichiometrically-weighted rate of the reaction.

For more information, please see the documentation in the Connectors package.
