Air Flow Rate (CFM) Calculation

The calculator will calculate the air flow rate based on given values of cubic inch displacement, engine speed and volumetric efficiency. CFM is a measure of air flow into and out of an engine.
Formula: CFM= (CID * RPM * VE) / 3456
Where, CFM (Cubic Feet per Minute) = Air Flow Rate, CID = Cubic Inch Displacement, RPM = Engine Speed, VE = Volumetric Efficiency
