bubbleDensity

Density of liquid phase w.r.t. saturation pressure | use setSat_p function for input

Information

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

This function calculates the liquid phase density of R134a from the state variable p (absolute pressure). It is modelled by cubic splines which are fitted with non-equidistant grid points derived from the fundamental equation of state of Tillner-Roth and Baehr (1994) and the Maxwell criteria.

Restrictions

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