How to Calculate Diffusivity by Film Theory?
Diffusivity by Film Theory calculator uses Diffusion Coefficient (DAB) = Convective Mass Transfer Coefficient*Film Thickness to calculate the Diffusion Coefficient (DAB), The Diffusivity by Film Theory formula is used to calculate the diffusivity for the liquid phase in contact with the other phase based on film theory when film thickness and mass transfer coefficient are known. Diffusion Coefficient (DAB) is denoted by D_{AB} symbol.
How to calculate Diffusivity by Film Theory using this online calculator? To use this online calculator for Diffusivity by Film Theory, enter Convective Mass Transfer Coefficient (k_{L}) & Film Thickness (δ) and hit the calculate button. Here is how the Diffusivity by Film Theory calculation can be explained with given input values -> 4.8E-5 = 0.0095*0.005.
