functiondBubbleEnthalpy_dPressure_der_sat
Time derivative of liquid specific enthalpy in two-phase region w.r.t. pressure
Extends from Modelica.Icons.Function (Icon for functions).
Information
This function calculates the time derivative of liquid specific enthalpy of R134a with regard to the time derivative of p. The non-derivative function is bubbleEnthalpy.
Restrictions
It is only valid in the two-phase region (i.e., ptriple ≤ p ≤ pcrit ).
