Divide the tank volume by 7.48 (7.48 equals the number of gallons in one cubic foot.) All you need to do is start filling the empty compressor i.e from 0 kg/cm to design pressure and record the time in mins. Converting scfm to acfm Equations and Calculator. This variable nature of air calls for standardization (based on air pressure and temperature). SCFM is calculated at a lower pressure which makes the air volume larger, and so, SCFM is always a bigger number than CFM. Note: To convert SCFM to SLPM, multiply by the factor 28.3168. 7:00AM - 3:30PM PSI (Pounds per Square Inch) is the Pressure. It is called the Gas Compressibility Factor, or Z-factor. Contrarily, a stationary compressor system for heavy-duty tools may need a CFM rating more than 10, at 100-120 psi. Apps can be a great way to help learners with their math.

Conversion Between Standard Flow (SCFM) and Actual Flow (ACFM). That can be an airflow generated by an air conditioner, furnace, ceiling fan, compressor, and other HVAC devices. Q = Flow rate (SCFM). In all those cases, we dont talk about pressures and temperatures; we only talk about the volumetric amount of air. If the compressor loads at 80 PSI and unloads at 120 PSI, this equals a 40 PSI difference (also known as differential pressure). The calculation is based on standard conditions. Knowing what each of them means will help us illustrate the main SCFM vs CFM differences: If you check the Ideal Gas Law, you can see why not all air (gas) is the same. The Actual Cubic Feet per Minute - ACFM - depends on the, The conversion from SCFM to ACFM can be expressed, ACFM = SCFM [Pstd / (Pact - Psat )](Tact / Tstd) (1), Pstd = standard absolute air pressure (psia), Pact = absolute pressure at the actual level (psia), Psat = saturation pressure at the actual temperature (psi), Tact = Actual ambient air temperature (oR).
