Correlation for stack friction factor?

Correlation for stack friction factor?

Correlation for stack friction factor?

(OP)
Does anyone know of a source for a correlation for friction factors in natural-draft stacks and chimneys, particularly small (let's say 2 ft and under) diameters?  I've seen the charts in Perry; naturally, those are rather small and not particularly spreadsheet-friendly.

RE: Correlation for stack friction factor?

You can also use the churchill equation, its more direct.
You still need the rugosity coefficient depending on the type of material.
