Reynolds Analogy

The following equation (Equation 6.69) is known as the Reynolds Analogy. It allows other parameters to be found if the velocity is known and vise versa. It consists of dimensionless parameters.

Where is Friction Coefficient, is Stanton number, and is the Mass Transfer Stanton number.

This analogy is further expanded by the Modified Reynolds analogy (Eq. 6.70):

And the Chilton-Colburn analogy:
