Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This function calculates the dynamic viscosity of R134a from the state record (e.g., use setState_phX function for input). The dynamic viscosity is modelled by the corresponding states method of Klein, McLinden and Laesecke (1997).

Restrictions

This property is only defined in one-phase region.
