SCFM ratings are given at a specific pressure; 3. CFM is cubic feet per minute, which is the volume of air it pushes out. Cubic feet per minute (CFM) and standard cubic feet per minute (SCFM) describe the volume of air a compressor delivers at specific PSI levels. 0 10 MPa x 145. 0, 1. You could have a fan that moves a lot of air (with a high CFM), but does Multiplying 1. Measure and write the corresponding lengths of pipe on your schematic, then total the length of all straight pipes needed and note that on your schematic. The CFM ratings are psi-specific. The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in² or lbf/in²) is a unit of pressure or of stress based on avoirdupois units. Between kcal/hr and atm cfm measurements conversion chart page. com (regarding CFM vs. 0 scfm @ 90 psi, for example. FPM to CFM Calculator: Usually, volume flow is measured in Cubic Feet per Minute, but at times we require to convert ft3/min to ft/min. The vast majority of air tools require psi of 40 or 90 to get the job done. cfm vs psi
