Easy laminar flow calibration.

Fan OFF

FAN ON. Just enough that candle flame angles @ 90 degree's _without blowing OUT - everywhere inside work area.

Laminar flow depends on the Reylonds number, and that depends on liquid viscousity, density, and diameter if you're calculating this for a pipe. Length (or the pipe, wing, whatever) will also play a role cause the flow will transition from laminar to turbulent if the reynolds number is too high. A good approximation is anything above 2300 is turbulent. What are you trying to do, figure out what fan specs you need or something?

100 feet per min is the recomendation .

If the flame of the candle candle goes down like that, the speed is way higher than 100 ft/min .
