Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This function calculates the time derivative of liquid specific entropy of R134a with regard to the time derivative of p. The non-derivative function is bubbleEntropy.
Restrictions
It is only valid in the two-phase region (i.e., ptriple ≤ p ≤ pcrit ).
