Talk:Sherwood number

empirical equation
I think for the empirical equation for the sherwood number as a function of the Reynolds and Schmidt number boundary conditions need to be given. Without a special case to aply the equation to it is useless.

when sh number are going to zero? —Preceding unsigned comment added by 80.66.183.39 (talk) 15:09, 27 October 2009 (UTC)

issue with the article
I am not specialist in Mass Transfer but describing the Sherwood number as the ratio of convective forces to diffusive forces for mass transfer seems wrong to me. It is rather the ratio of the total magnitude of mass transfer to the mass transfer caused by diffusive forces only. Sh informs about the importance of diffusion in the global mass transfer: When Sh is low (approaches 1), diffusion dominates whereas when Sh is high (tends to infinity) other phenomena such as forced convection dominate mass transport. Note that the ratio of convective forces to diffusive forces for mass transfer is the Peclet number.
