Abstract:
Beyer's B/A parameter for liquids can be calculated using an analytical PVT equation of state supplemented with specific heat data. Results for two equations will be investigated: the Tait equation and our own. The calculations of sound speed, sound speed derivatives, and the two components of B/A will be compared with experimental data for a series of normal alkane liquids. A comparison of these results with the prediction of Ballou's rule (linear relation of B/A vs 1/c) will be presented. Tentative conclusions about the relative utility of the two equations will be presented as well as the outlook for the approach using any PVT equation of state.
