WebRPM to SFM Formula. Of course we can easily convert RPM to SFM by manipulating the following equation: SFM = RPM * Circumference. That’ll get your from surface feet per minute to rpm. [ For more formulas, check our Cutting Speed Formulas Article. WebMay 17, 2024 · Formula: CFM2 = CFM1 X (RPM2 ÷ RPM1) or RPM2 = RPM1 X (CFM2 ÷ CFM1) What it means: As you increase fan RPM, CFM increases at a 1:1 ratio. So if you need to increase CFM by 10%, your RPM has to increase by 10%. Since it is a 1:1 ratio, we can interchange RPM for CFM in Fan Laws 2 and 3. We use Fan Law 1 all the time in the field. grundy county circuit clerk court records https://lovetreedesign.com
