Knudsen dimusion in a porous solid Porves silica gel is used to adsorb propane from helium at 373K and 1atm. Drical values of parameters for porous silica gel are as follows: porosity =0.486, Dricacity =3.35, and pore diameter =22A (a) Calculate the Knudsen number for diffusion inside the pores. (t) Calculate the effective diffusivity of propane under these conditions. Answer: 0.045mm2/s
