ELECTRO-OSMOTIC FLOW. Shahrood University Of Technology. Presenter : Ahmad Hadadan 9124494 Adviser : Dr.Nazari. 1 /14. Pressure Driven Flows. This flow is caused by the pressure gradient at up & down stream of channel.
Water and Osmotic Regulation. Chapter 8. Water Balance and Concentration. Internal Environment = aqueous solution Volume and composition must be maintained within narrow limits Composition different from external environment
Water Flow. And Deposition. By:Jessica Munn Bailey Northrup Heather MacFarlane. Definitions. Deposition-the process of erosion stops when the transported particles fall out of the transporting medium and settle on a surface.
n. π = RT. V. Osmotic Pressure. For dilute solutions of nonelectrolytes:. π V = nRT. = MRT. Osmotic Pressure.
Osmotic Solutions. Equal concentration of solute. Higher concentration of solute. Lower concentration of solute. H 2 O. Solute molecule. Selectively permeable membrane. Water molecule. Solute molecule with cluster of water molecules . Net flow of water. Osmosis.
Osmotic potential. Occurs in plant cells due to the cell wall (and fungi somewhat). The movement in and out of an animal cell is driven by the relative solute concentration gradient (after obeying the electrochemical gradient) Animal cells may swell, burst, or may crenate
