fuel % evaporated vs temp graphs at reduced pressure
fuel % evaporated vs temp graphs at reduced pressure
(OP)
Dear Ladies and Gentlemen
Is it possible to find somewhere on the web "S" diagrams (% evaporation vs. temperature) for gas turbine fuels (e.g. JP4, JP5 etc.) but for nonstandard ambient pressures (lower than 14.7 psia=1 atm).
I am trying to estimate a fuel pump cavitation intensity at an inlet pressure of about 10 psia (0.7 atm) and I was not able to find relevant data on the web.
Thank you in advance, Rad.

RE: fuel % evaporated vs temp graphs at reduced pressure
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

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

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.

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.
