Volume Correction Factors by Velocity of Sound

This report presents work, including laboratory measurements on a large number of hydrocarbon liquids, which demonstrates that the expansivity of hydrocarbon mixtures is better predicted by using a combination of density and velocity of sound in the liquid, than by density alone.

The work was organised through the Energy Institute (Institute of Petroleum) Oil Transportation Measurement Committee, PM-L-4, and carried out by H&D Fitzgerald Limited. The project was managed and coordinated by Melverley Consultants Limited.
