The following data are obtained for an ultrafiltration experiment with an oil emulsion in a tubular module with an internal diameter of 17 mm and a length of 0.5 m at 25 C. The applied pressure is 6 bars and the cross flow velocity is 4 m/s. The viscosity of the emulsion is 1.5 x 10-3 Pa.s and the density is 1 g/cm3. The emulsion droplets have a diameter of 0.2 microns. Calculate the mass transfer coefficient from the experimental data assuming that the film model applies (i.e. Langmuir boundary layer). Youll need to use the Sherwood number correlations. *hint* The diffusion coefficient is determined by the Stokes-Einstein equation, =/ 6rp where k, T, , , rp are the boltzmanns constant, temperature in kelvin, viscosity and particle radius, respectively. Given, Concentration Wt% 0.4,0.6, 0.8, 1.2 and Flux (LMH) 85 ,83, 81, 78.
