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