.ThermofluidStream.Media.XRGMedia.R1234yf_ph.dDewDensity_dPressure

Information

This function calculates the derivative of vapor density of R1234yf in two-phase region with regard to the state variable p (absolute pressure). The non-derivative function is dewDensity.

Restrictions

It is only valid in the two-phase region (i.e., p_triple ≤ p ≤ p_crit ).
