Air Flow Rate (CFM) Calculation


The calculator will calculate the air flow rate based on given values

Cubic Inch Displacement  inch3
Engine Speed  rpm
Volumetric Efficiency  

 

 

Air Flow Rate: ft3/min

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
