Flag. CFM Pipe Size Chart. Let’s get straight into it, the following chart will help you gain a better understanding of the pipe size you need depending on the volume of airflow you have running through it, and its …SCFM represents standard cubic feet per minute while CFM most likely represents actual cubic feet per minute. Because it's volume based, the flow rate will be temperature and pressure dependent. If you're looking at the flow rate of a single process stream, the SCFM will represent the flow at 14.7 psia and 60 F (or close to it). Let’s put all of this in the equation like this: CFM (8×10 Duct) = 800 FPM × 0.66 Ft × 0.83 Ft = 438 CFM. In short, an 8×10 inch duct at 700 FPM air velocity has a 438 CFM air flow.
