6. (25 points) Data have been obtained for various concentrations of insulin by ultrafiltration (crossflow filtration) as shown in the table below. Using these data and the provide grid paper, determine the followings. Insulin concentration Ultrafiltration flux (wt. %) (ml cm 2 min) 1.0 0.055 2.0 0.042 5.0 0.023 10.0 0.008 (a) For the ultrafiltration of 5.0 wt.% solution of insulin, determine the polarization modulus. (b) Determine the mass transfer coefficient in a correct unit. 6.
