Osmotic pressure is expressed in terms of the change in the activity of the solvent a1 when a solute is present. According to the Gibbs-equation, the activity a1 is related to the mole fraction of the solute (notation here: 1-solvent, 2-solute). Since by definition the mole fraction is...
If both compartments are open to the atmosphere – that is, exposed to the same pressure – then water will pass from the first compartment into the second in an attempt to equalise the chemical potentials on both sides. However, no matter how much water passes from compartment 1 to ...

It is shown that the osmotic pressure of a colloidal dispersion can be interpreted as the isotropic part of the macroscopic particle stress in the suspension. The particle stress is in turn expressible in terms of hydrodynamic interactions among the suspended particles. Thus, there is a completely...
The experiment is quite simple: pure solvent is introduced into one side of a cell that is separated into two parts by a semipermeable membrane. The polymer solution is placed in the other side, which is enclosed and connected to a manometer or some other kind of pressure gauge. As solvent...
Osmosis is the transfer of solvent from a region of lower concentration to a region of higher concentration. Explore more about the definition of osmosis and osmotic pressure.
The concept of an internal pressure gradient in a rigid porous has been proposed as the basis for osmotic flow. The origin of the pressure in terms of the theory of the chemical potential implies also the existence of states of negative pressure, that is, tension. These states have been obs...
Osmotic pressure is that pressure needed to keep a solvent (no or low solute concentration) from passing across a semipermeable membrane into a solution containing dissolved solutes (high solute concentration). Being able to control the osmotic pressure is important to living cells, especially animal...
Osmotic pressure is produced in the narrow spacing between the flexible reservoir wall and the rigid semipermeable compartment. The reservoir is gradually reduced in volume and the solution of the active agent is forced to exit through the flow moderator at a controlled rate (Theeuwes, 1975; ...
In an osmotic system, the rate of water imbibition into the system in terms of volume can be expressed as: (19.18)dVdt=Akl(Δπ−ΔP) dV/dtis the rate of water flow,kis the hydraulic permeability,Ais the membrane area,lis the thickness, Δπis the osmotic pressure difference, and Δ...
