WOLFRAM SYSTEM MODELER
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This function calculates the time derivative of vapor density of R134a with regard to the time derivative of p. The non-derivative function is dewDensity.
It is only valid in the two-phase region (i.e., ptriple ≤ p ≤ pcrit ).
Description: Time derivative of vapor density in two-phase region w.r.t pressure
