.ThermofluidStream.Media.XRGMedia.R1234yf_ph.dBubbleDensity_dPressure_der_sat

Information

This function calculates the time derivative of liquid density of R1234yf with regard to the time derivative of p. The non-derivative function is bubbleDensity.

Restrictions

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