Membrane Water Concentration Based on Solution Diffusion Model Calculator

Membrane Water Concentration Based on Solution Diffusion Model is a model for the transport of water and solutes through a membrane. It is based on the assumption that water and solutes dissolve in the membrane material and then diffuse through the membrane down a concentration gradient and is represented as C_w = (J_wm*[R]*T*l_m)/(D_w*V_l*(ΔP_atm-Δπ)) or Membrane Water Concentration = (Mass Water Flux*[R]*Temperature*Membrane Layer Thickness)/(Membrane Water Diffusivity*Partial Molar Volume*(Membrane Pressure Drop-Osmotic Pressure)). Mass Water flux is defined as the rate of movement of water across a surface or through a medium, Temperature is a physical quantity that expresses quantitatively the attribute of hotness or coldness, Membrane Layer Thickness is the distance between the two outer surfaces of a membrane. It is typically measured in nanometers (nm), which are billionths of a meter, Membrane water diffusivity is the rate at which water molecules diffuse across a membrane. It is typically measured in square meters per second (m^2/s), The partial molar volume of a substance in a mixture is the change in volume of the mixture per mole of that substance added, at constant temperature and pressure, Membrane pressure drop is the difference in pressure between the inlet and outlet of a membrane system, housing (pressure vessel), or element & Osmotic pressure is the minimum pressure that must be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane.
