This function shall be used in order to calculate the thermodynamic state record for the vapor phase boundary. It requires the saturation record as input which can be determined by both functions setSat_p and setSat_T:

Example:

Medium.AbsolutePressure p=3e5;
// Viscosity on the vapor phase boundary
SI.DynamicViscosity eta_vap;

equation

eta_vap = Medium.DynamicViscosity(Medium.setBubbleState(Medium.setSat_p(p)));

Restrictions

It is only valid in the two-phase region (i.e., p_triple ≤ p ≤ p_crit ).
