Sherwood Number

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Sherwood number, abbreviated as Sh, a dimensionless number, is the ratio between convective mass transfer and diffusive mass transfer.

 

Sherwood Number formulas

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

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

Symbol English Metric
\(\large{ Sh }\) = Sherwood number \(\large{dimensionless}\)
\(\large{ l_c }\) = characteristic length \(\large{ft}\) \(\large{m}\)
\(\large{ D }\) = diffusion coefficient \(\large{\frac{ft^2}{sec}}\) \(\large{\frac{m^2}{s}}\)
\(\large{ K }\) = mass transfer coefficient \(\large{dimensionless}\)
