What is Wilke Chang Equation for Liquid Phase Diffusivity ?
Wilke and Chang have proposed this correlation to estimate the diffusivity of nonelectrolytes in an infinitely dilute solution.
In this equation, DAB [m2/s] is the diffusivity of A in very dilute solution in solvent B, MB is molecular weight of solvent B (the solvent), T [K] is absolute temperature, µ [kg/m.s] is viscosity of solvent, vA is solute molar volume at its normal boiling point m3/kmol, and ΦB is the association factor of solvent B.
How to Calculate Wilke Chang Equation for Liquid Phase Diffusivity?
Wilke Chang Equation for Liquid Phase Diffusivity calculator uses Diffusion Coefficient (DAB) = (1.173*(10^(-16))*((Association Factor*Molecular Weight B)^(1/2))*Temperature of Gas)/(Dynamic Viscosity of Liquid*((Molar Volume of Liquid/1000)^0.6)) to calculate the Diffusion Coefficient (DAB), The Wilke Chang Equation for Liquid Phase Diffusivity formula is defined as an empirical correlation proposed by Wilke Chang in 1955 for estimating liquid phase diffusivity. Diffusion Coefficient (DAB) is denoted by DAB symbol.
