Air Flow Rate (CFM) Calculation

The air flow rate based on selected 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
