dynamicViscosity

Dynamic viscosity w.r.t. temperature and density | use setState_phX function for input

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.
