.ThermofluidStream.Media.XRGMedia.R134a_ph.velocityOfSound .ThermofluidStream.Media.XRGMedia.R134a_ph.velocityOfSoundThis function calculates the velocity of sound of R134a from the state record (e.g., use setState_phX function for input). The velocity of sound is modelled by the fundamental equation of state of Tillner-Roth and Baehr (1994).
This property is only defined in one-phase region.
