calculation of gas viscosity
calculation of gas viscosity
(OP)
Hi all,
I would like to ask for a reference (basic formula) to obtain the viscosity (the one in Cp unit) of gases (mixtures are composed of Hydrocarbons and non-HC such N2, H2, etc. any of which could be given at any percentage).
It does not need to be precise, a +/- 10% will do. So by lowering the bare as for accuracy , I would have hoped there could be some "magic" formula. To push the "effrontery"....pressures may also go quite high (high means can be tens of Mbar).
So far I consulted the methods available on the API TDB. I am exploring that.
However any hint to a further reference (for calculation or to educate myself on the topic) will be appreciated.
Thanks!

Good luck,

Sorry can't seem to get the attachment showing the equations from the API TDB to upload :(

I am also studying the document referred to by chicopee. Appreciate that.
