A class for viscosity model that is defined by The International Association for the Properties of Water and Steam IAPWS

With the definition, the viscosity is a function of temperature and water density

Attention

The critical enhancement, \(\bar{\mu}_2\), which is significant only within the boundaries specified by

\[ T (\mbox{in K}) \in (645.91, 650.77) \]

and

\[ \rho (\mbox{in kg m}^{-3}) \in (245.8, 405.3)\]

, is not considered.
