WOLFRAM SYSTEM MODELER
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This function calculates the derivative of vapor entropy of R134a with regard to the state variable p (absolute pressure). The non-derivative function is dewEntropy.
It is only valid in the two-phase region (i.e., ptriple ≤ p ≤ pcrit ).
Description: Saturation properties | pressure is used for interpolation
Description: Derivative of vapor specific entropy in two-phase region w.r.t pressure
