Air Flow Rate
air flow rate formula
| \(\large{ CFM = \frac {CID \; RPM \; VE} {3456} }\) |
Where:
| Units | English | Metric |
| \(\large{ CFM }\) = cubic feet per minute | \(\large{\frac{ft^3}{min}}\) | \(\large{\frac{m^3}{s}}\) |
| \(\large{ CID }\) = cubic inch displacement | \(\large{in^3}\) | \(\large{mm^3}\) |
| \(\large{ RPM }\) = engine speed | \(\large{\frac{rotation}{min}}\) | \(\large{\frac{rotation}{s}}\) |
| \(\large{ VE }\) = volumetric efficiency | \(\large{dimensionless}\) | |
