14.7. Porous membrane with pressure differential. Water at 70°C passes through a polyethylene membrane of 25% porosity with an average pore diameter of 0.3 µm and an average tor- tuosity of 1.3. The pressures on the downstream and upstream sides of the membrane are 125 and 500 kPa, respectively. Estimate the flux of water in m³/m²-day.
