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.

You still need the rugosity coefficient depending on the type of material.
