Abstract of the paper ``Analysis of ultrasonic velocities in hydrocarbon mixtures''
Ultrasonic velocity data on hydrocarbon mixtures was shown by
Wang and Nur [JASA 89, 2725 (1991)] to agree quite well with the
predictions of a simple mixing rule (volume average of velocity).
The same data is reanalyzed using Wood's formula and the
time average approximation. Wood's formula for acoustic velocity is
shown to be always less than the time average formula, which is itself always
less than the simple mixing rule result. Although the volume average rule
agrees best with the data on binary mixtures of 1-decene and
1-octadecene, all these formulas agree with the data to within 1 %
and, therefore, it is not possible to distinguish among the formulas
using this data set.
Similar results are also found for six multicomponent hydrocarbon mixtures.
