Sherwood Number

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Sherwood number ( \(Sh\) ) (dimensionless number) is the ratio between convective mass transfer and diffusive mass transfer.

Sherwood Number formula

\(\large{ Sh = \frac { K l_c}    {D}  }\)         

Where:

\(\large{ Sh }\) = Sherwood number

\(\large{ l_c }\) = characteristic length

\(\large{ D }\) = diffusion coefficient

\(\large{ K }\) = mass transfer coefficient

Solve for:

\(\large{ l_c = \frac { Sh D}    {K} }\)

\(\large{ D = \frac { K l_c}    {Sh} }\)

\(\large{ K = \frac { Sh D}    {l_c} }\)
