The vapor pressure of a liquid is defined as the pressure exerted by the molecules that escape from the liquid to form a separate vapor…

Kerosene jet fuel typically has 50 pS m-1 conductivity. Although the conductivity is an underlying characteristic of petroleum liquids, there is an inconsistency on the…

Viscosities at the temperature of flight are relevant to performance, and accordingly review of a study of the viscosities of jet fuels at such temperatures…

The temperature at which wax appears is an important factor in jet fuel specification. At the cloud point wax appears6. Specification for jet fuels take…

A typical density for a kerosene jet aircraft fuel would be 780 kg nr3 or 50°API. Of course, there is a large difference between the…

In the distillation of crude oil there is a gap between gasoline and kerosene, the fraction known as naphtha. Unprocessed naphtha is unsuitable for blending…

Oil and gas in a deep well are of course significantly higher in temperature than ambient. Natural gas, associated or non-associated, on cooling releases hydrocarbon…

When the Reid Vapour Pressure is measured there is air in the confined space which was previously dissolved in the test sample. Corrections for this can…

There is of course no such thing as ‘the vapour pressure’ of a gasoline. This is because the observed vapour pressure depends upon the volume…

Methanol-gasoline fuels do exist, but there is not the same degree of use as there is with ethanol-gasoline fuels. This is not difficult to understand.…
