Aeration Number

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Aeration Number, abbreviated as \(N_a\), a dimensionless number, is used for the agitated mixing of gas and liquids.

Aeration Number Formula

\(\large{ N_a = \frac{ Q }{ n \; d^3 }  }\)

Where:

\(\large{ N_a }\) = Aeration number

\(\large{ Q }\) = gas volumetric flow rate

\(\large{ n }\) = rotational speed

\(\large{ d }\) = impeller diameter
