How to know SCFM AND CFM?
Â
SCFM (standard cubic feet per minute) and CFM (cubic feet per minute) are units of measurement to describe the flow rate of air or gas. SCFM is a measure of the volume of air flowing through an air compressor at standard conditions (usually 68°F and 14.7 psi). CFM is a measure of the volumetric flow rate of compressed air at the actual conditions of the air compressor.
Â
To convert SCFM to CFM, you need to know the actual temperature, pressure, and relative humidity of the compressed air. The formula to convert SCFM to CFM is:
CFM = SCFM x (psia / 14.7) x (530 / Tactual) x (actual RH / 100)
Â
Where:
- CFM = Cubic feet per minute at actual conditions
- SCFM = Standard cubic feet per minute
- psia = Actual pressure in pounds per square inch absolute (psia)
- Tactual = Actual temperature in degrees Fahrenheit (°F)
- actual RH = Actual relative humidity in percent (%)
Â
For example, if you have a compressor that delivers 20 SCFM at standard conditions and you want to know the flow rate at actual conditions of 90°F, 100 psig, and 70% relative humidity, then you can use the formula as follows:
CFM = 20 x (100 / 14.7) x (530 / 90) x (70 / 100)
CFM = 20 x 6.80 x 5.89 x 0.70
CFM = 541.8
Â
Therefore, the flow rate of the compressor at actual conditions is approximately 541.8 CFM.
