.ThermofluidStream.Media.XRGMedia.R1234yf_ph.isobaricExpansionCoefficient .ThermofluidStream.Media.XRGMedia.R1234yf_ph.isobaricExpansionCoefficientThis function calculates the isobaric expansion coefficient of R1234yf from the state record (e.g., use setState_phX function for input). The isobaric expansion coefficient is modelled by the fundamental equation of state.
This property is only defined in one-phase region.
