Sherwood Number relates the mass transfer coefficient to mass diffusivity. It is known to be proportional to the length ok
diffusion L.
a Determine the formula of the Sherwood Number if it is only dependent on the three quantities (mass transfer
coefficient ke, mass diffusivity DAB and length of diffusion L.)
b. A certain liquid at ambient temperature has k. = 0.078 m/s and DAn of 0.125 cm2/s, diffuses into a water
in a chamber of length 5 m. If ink of the same Sherwood Number has k. = 0.02 m/s diffuses in water in the
same chamber, calculate the mass flux of the ink if the concentration gradient across the diffusion length is 15
g/cm
