Experiments indicated that adsorptive forces lower the potential energy of water inside uncharged cellulose acetate membranes. As a result it is postulated that the steady‐state pressure distribution during osmosis is affected. In particular, a sudden rise in pressure should occur across the water‐membrane interface. Thus, in this region, water may flow against a pressure gradient.
