How To Calculate Scfm Of An Air Compressor?
To calculate SCFM (Standard Cubic Feet per Minute) on an air compressor, you’ll need to know the machine’s PSI (Pounds per Square Inch), CFM (Cubic Feet per Minute), and the standard atmospheric pressure.
Here are the steps to follow:
1. First, find the machine’s PSI and CFM ratings. These are typically stated in the user manual or on the compressor’s nameplate.
2. Next, use the formula: SCFM = CFM x (Pactual / Pstandard), where Pactual is the actual pressure and Pstandard is the standard atmospheric pressure, which is approximated to 14.5 PSI.
3. Substitute the values you’ve obtained from the compressor into the formula to get the SCFM.
Remember, this calculation gives you the SCFM at the current atmospheric pressure. Hence, it might vary with changes in weather and altitude.
Factors That Affect The Scfm Rating Of An Air Compressor:
Main factor that affects the SCFM (Standard Cubic Feet per Minute) rating of an air compressor are as under:
1. Engine Power:
