fuel % evaporated vs temp graphs at reduced pressure 1

PS to the above query.

Formal term used for what I am asking for is:

"Boiling Range Distribution" diagrams for jet fuels

But not the standard ones, at atmospheric pressure (tests per ASTM D2887 or D3710 etc.). I would like to find the diagrams at reduced pressures, around 0.7 of standard atmospheric (barometric) pressure.

Thanks Rad

I have not seen these curves. What is a fuel pump cavitation index, maybe there is some other way to generate the data you need?

TD2K thank you for the imput. It seams that fuel pumps do not have cavitation index. Better to say it is impossible to calculate it because there is no single, a unique pv (vapour pressure) or maybe I am wrong. As fare as I know fuels are compounds of several hydrocarbons (that is more your field than mine) with various boiling points.

Nevertheless I should contact the pump manufacturer (if it still exists) and bug those guys.

Thanks, Rad

Jet fuels do have a vapor pressure even though they are made up a mixture of hydrocarbons. The vapor pressure is not 'uniquely' fixed but it won't vary much.

See thread124-27883 for a discussion how to estimate the vapor pressure off the flash temperature. The API data books (or a manual calc) will allow you to estimate the vapor pressure at another temperature.

Sir TD2K (I suppose that you are not a Lady),

You are really one of the most helpful and knowledgeable member of all the forums. Thank you very much again and all the best to you.

No, you're right, I'm not a lady. But, I'm also not much of a gentleman either ;-)

Glad I could help.
