Information

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

This function calculates the time derivative of liquid density of R134a with regard to the time derivative of p. The non-derivative function is bubbleDensity.

Restrictions

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