A sintered solid of silica 2.00 mm thick is porous with a void fraction of 0.8 and a tortuosity of 3.0. The pores are filled with water at 300K. At one face the concentration of NaCl is held at 0.8 g mol/liter, and fresh water flows rapidly by the other side. Neglecting any other resistances but that in the porous solid, calculate the diffusion of NaCl at steady state.
