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 specific entropy of R134a with regard to the time derivative of p. The non-derivative function is dewEntropy.
It is only valid in the two-phase region (i.e., ptriple ≤ p ≤ pcrit ).
Description: Derivative of vapor specific entropy in two-phase region w.r.t pressure
