Plan for 3,000 to 4,000 feet per minute of velocity in the duct to help prevent buildup inside the duct. Enter Duct Airflow (CFM), Duct Velocity (FPM), Duct Length and the number of bends. In other words, FPM is a measurement of how fast the air moves and CFM measures how much air is moved. For example, in a hood which has an inadequate evacuatory volume and consequently a face velocity of, say, 25 feet per minute (fpm), one could increase the face velocity to 100 fpm by lowering the sash three quarters of the way (thus reducing the face area). Cubic Feet Per Minute (CFM) = Feet Per Minute x Area of Air Space. air flow level requires a velocity of 25. 10 lbs PM/1,000 lbs air) x (8,760 hrs/yr) x (1 ton/2,000 lbs) = tons PM/yr * dry standard conditions Table 2: Permitted Emission Unit A. ÷ by 192 lineal inches = 2.
