functiondBubbleEnthalpy_dPressure_der_sat
Time derivative of liquid specific enthalpy in two-phase region w.r.t pressure
Extends from Modelica.Icons.Function.
Information
This function calculates the time derivative of liquid specific enthalpy of R1234yf 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 ).
