functiondBubbleEnthalpy_dPressure
Derivative of liquid specific enthalpy in two-phase region w.r.t. pressure
Information
This function calculates the derivative of liquid enthalpy of R134a with regard to the state variable p (absolute pressure). The non-derivative function is bubbleEnthalpy.
Restrictions
It is only valid in the two-phase region (i.e., ptriple ≤ p ≤ pcrit ).
