AVGAS viscosity
AVGAS viscosity
(OP)
I am looking for information on the kinematic viscosity of AVGAS 100LL versus temperature. In particular I wish to find it at temps below ambient.
Has anyone point me to where I might find this?
Thanks!

Regarding standards, ASTM D 910 applies to aviation gasolines. I see no mention of viscosity. No hits searching IHS for aviation gasoline viscosity. Searching just gasoline viscosity yields five ASTM standards for automitive engine oils.

RE: AVGAS viscosity
I also need the s.g. at a lower temp so I will post that question now.

PRODUCT NAME = GASOLINE
SG60 @ 60 F = 0.741
EXPANSION_COEFF 1/Fº = 0.0005
BULK_MOD = 100000*EXP(1.9947-0.00013427*TF-0.79392/SG60^2-0.002326*TF/SG60^2)
DEN_pcf = 62.4*(SG60-EXPANSION_COEFF *(TF-60))/(1-PSIG/BULK_MOD)

Be interesting to find out how they compare as this spreadsheet uses the ASTM expression for 2cst and over (it gets a bit too complex at lower viscosities).

Thanks for the spreadsheets. They look interesting. I shall see what I can do with them. But my viscosity is about 1cS at 40C so that one will not work.
