Show transcribed image text Assignment problem 3.4: Show that for equi-molar counter-diffusion from a sphere to a surrounding stationary infinite medium, the Sherwood number (Kd/DAB) based on the diameter of the sphere is equal to 2. Kg is the mass transfer coefficient, d is the diameter of sphere and DAB is the molecular diffusivity.
