The hydrostatic pressure exerted by a solution across a semipermeable membrane from a pure solvent; the pressure needed to counteract osmosis
(physical chemistry) the pressure exerted by a solution necessary to prevent osmosis into that solution when it is separated from the pure solvent by a semipermeable membrane
pressure placed on a semipermeable membrane by the passage of a solution into a pure solvent
The pressure exerted by the flow of water through a semipermeable membrane separating two solutions with different concentrations of solute
