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.

Exhaust

by measureup » Fri Dec 09, 2005 2:57 am

I have a German document indicating that I need 20 m/s or 1450 m3/h for wood working exhaust. A dust collector is rated in cfm and the velocity of the air moving past an opening is in feet per minute. I have a velometer that measures feet per minute. With that in mind what reading will I need to meet 20 meters per second or 1450 cubic meter per hour?
