Science Buddies: "Ask an Expert"

i'm writing a research plan for my scince fair project "does the viscosity of different oils share the same temperature dependence?" i used the viscosity formula given byb this website but i cannot find the same one or another one anywhere else. do you have ay idea where this one was located so i can sight that in my sources as well?
thanks!
(ps i need this asap)

I am having trouble locating the formula you mention, could you please provide a URL for the page containing it?

Meanwhile, there are several formulae in Wikipedia:

http://en.wikipedia.org/wiki/Temperatur ... _viscosity

From that page I gather that the kinematic viscosity of fluids versus temperature is found empirically rather than from first principles.
