Calculate the average velocity for the filter.

3.Determine the filter’s conversion factor from the table.

4.Calculate the filter’s volume in CFM (m3/hr) by multiplying the average velocity by the conversion factor.

5.Calculate the hood’s volume by repeating the process for the remaining filters and summing the individual filter volumes.
