Flexible Duct Cfm Chart
Flexible Duct Cfm Chart - Flex duct has a higher pressure drop and as such may require the size shown on this guide be increased by 1 round size for up to 800 cfm and 2 round sizes above 800 cfm to insure proper airflow. Conversion of cfm to fpm also can be made. Flexible return ducts or (1) very short flexible 18” duct to move the 1000 cfm required by the 2.5 ton system. Addendum u expands the prescriptive duct sizing table (table 5.3) to account for the larger flows sometimes encountered with kitchen exhaust. Enter round duct diameter (inches), duct airflow (cfm), duct length and the number of bends. Friction loss chart friction loss data is shown above in inches of water gauge per 100 feet of straight duct. Note also the return air grille sizing formula at the top of the chart.

Friction loss chart friction loss data is shown above in inches of water gauge per 100 feet of straight duct. The chart is based on metal duct.
The chart is based on metal duct. Values may be arrived at if eithercfm or fpm for a given duct diameter is known. Conversion of cfm to fpm also can be made. Pressure drop is the available static pressure (asp) allocated to the duct work. Tel is the total effective length of the longest supply run and the longest return run. The chart may also be used in converting cfm to fpm.
