Spec Grav and Spec Heat Values For Throttling Calc
Spec Grav and Spec Heat Values For Throttling Calc
(OP)
Hello all,
I'm trying a quick calculation of temp rise through a throttling valve. My fluid is Mil-PRF-83283, a synthetic hydrocarbon base hydraulic oil. The basic operating temp upstream of the valve is 110 deg F.
Using an equation derived by Henke which requires specific gravity and specific heat. I cannot find these values anywhere, not from the manufacturer (Anderol) and not the Govern office in charge of this specification. Web search not fruitful either.
Can anyone advise on this information please? Also in need of Vapor pressure data. Other advice appreciated.
Thanks
Tom

MSDS - 83283
All you need is there.

I have the MSDS, and it cites "Not available" for Vapor Pressure, does not mention Specific Heat at all, and provides Spec Grav at 60 deg F only.
Hoping someone knowledgable with Hydraulic fluid can suggest a similar oil with available values.
Thanks.

Replacement for the old 5606 aircraft hydraulic fluid, been out since about 1988.
Spec. Gravity= 0.84
vapor pressure= <0.02
vapor density=<7
boiling point= 520F/271C
Not that special of fluid, any good low temp operating fluid on market will due.
Type in MSDS 83282B in serach and it will come up. Will not get spec gr. at different temps unless you know somebody in mfg, or calculate it out. Simply call mfg, most will provide more information if you have a good reason to have this data.
