(a) Calculate the apparent mass-transfer coefficient for latex from the ultrafiltration results shown in Fig. 29.25. 

(b) Using the corresponding data for albumin as a reference, estimate the shear-induced diffusivity D_s for the latex spheres, and compare this with the normal diffusivity D_v. 

(c) What shear rate would be needed to explain the value of D_s?
