Sherwood Number

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

Sherwood Number formula

\(Sh = \frac { K l}    {D} \)          \( Sherwood \; number \;=\;  \frac { mass \; transfer \; coefficient  \;\;x\;\;   characteristic \; length }    { diffusion \; coefficient } \)

Where:

\(Sh\) = Sherwood number

\(K\) = mass transfer coefficient 

\(l\) = characteristic length

\(D\) = diffusion coefficient

Solve for:

\(K = \frac { Sh D}    {l} \)

\(l = \frac { Sh D}    {K} \)

\(D = \frac { K l}    {Sh} \)
