	~~The '''Sherwood number''' ('''Sh''') (also called~~ the '~~''mass transfer [[Nusselt number]]''') is~~ a ~~[[dimensionless number]] used in mass-transfer operation~~. ~~It represents~~ the ~~ratio of [[convection\|convective]] to [[diffusion\|diffusive]] mass transport~~, ~~and is named in honor~~ of ~~[[Thomas Kilgore Sherwood]]~~.
