convert air flow to air velocity
Forum rules
Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

Yes, if you know the cross sectional area of the tube or duct it is flowing through. If you know the flow rate in cu ft/min, and the area, division will give you the flow rate in feet/minute. You can apply conversion factors to change the units.
Note the velocity computed is an average across the duct. Fluid mechanics is complex, but velocity will be higher in the center, zero at the duct walls, and build from zero at the walls to the central value according to a complex calculation. Since gases have low viscosity, the region where the velocity exhibits this behavior is fairly small.
