When calculating how much your air compressors output rate needs to be, you not only need to consider the requirements of each of your tools, but also how often/how long they will run for. SMC Part Builder. Divide the value by 7.48. SCFM. Converting the flow rate from CFM (compressed air) to SCFM (free air) can be calculated as follows: P = Pressure (PSIG) SCFM = CFM x (P + 14.7) / 14.7; Knowing how to use these calculations help with the sizing of the system components as well as calculation of the total air consumption of the system. kJ. To account for the deviation from the ideal situation, another factor is included. Using this SCFM to CFM formula, we can devise a calculator that converts SCFM to CFM automatically. Because of this, we use SCFM for a more accurate indicator of a compressors air capacity. For SCFM-part, we know that this AC will generate 400 SCFM of airflow. This app definitely deserves a 5 star review I recommend it to anyone who is struggling with math. PSI is the measure of force that's applied to a defined area, and determines the . Standard Pressure (Ps) There is no standard pressure condition in CFM. My favorite feature is the camera, it has got me through some tricky assignments but has also really helped me understand math better. Divide the tank volume by 7.48 (7.48 equals the number of gallons in one cubic foot.) Google use cookies for serving our ads and handling visitor statistics. Credit Application. To adequately convert SCFM to CFM, we use the following SCFM to CFM formula: CFM = SCFM (14.7 psi Pactual ) (Tactual + 459.67) (68F+459.67). Psig is the compressed air pressure in pounds per square inch (gauge not absolute) And CFM is the resulting flow rate in standard cubic feet per minute. 93 Cv and it will meet the flow conditions. SCFM differs from CFM mainly in that SCFM has these variables fixed. Luckily, we've got what you need exactly, and that's the NorthStar Single Stage 2HP Air Compressor.
