An experiment is carried out to study the flow of water through an MF membrane. A 75 mm thick PES membrane has an average porosity of 0.35 is used for the experiment. Pure water flux through the membrane is 25 m3/m2 h at a pressure drop of 1.2 bar at 25 oC. The average pore size is estimated to be 1 μm. Calculate the tortuosity factor of the pores, the resistance to flow offered by the membrane, and its water permeability. The viscosity of water at 25 oC is 0.9 cP.
