.ThermofluidStream.Media.XRGMedia.R134a_ph.dBubbleEnthalpy_dPressure

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., p_triple ≤ p ≤ p_crit ).
