What is Molar diffusion?
Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of higher concentration to one of lower concentration. Once the concentrations are equal the molecules continue to move, but since there is no concentration gradient the process of molecular diffusion has ceased and is instead governed by the process of self-diffusion, originating from the random motion of the molecules. The result of diffusion is a gradual mixing of material such that the distribution of molecules is uniform. Since the molecules are still in motion, but an equilibrium has been established, the end result of molecular diffusion is called a "dynamic equilibrium".
How to Calculate Convective Mass Transfer Coefficient?
Convective Mass Transfer Coefficient calculator uses Convective Mass Transfer Coefficient = Mass Flux of Diffusion Component A/(Mass Concentration of Component A in Mixture 1-Mass Concentration of Component A in Mixture 2) to calculate the Convective Mass Transfer Coefficient, The convective mass transfer coefficient is an important parameter, since it is a measure of the resistance to mass transfer between the fluid flowing in a duct and the surface of the duct. Convective Mass Transfer Coefficient is denoted by kL symbol.
How to calculate Convective Mass Transfer Coefficient using this online calculator? To use this online calculator for Convective Mass Transfer Coefficient, enter Mass Flux of Diffusion Component A (ma), Mass Concentration of Component A in Mixture 1 (ρa1) & Mass Concentration of Component A in Mixture 2 (ρa2) and hit the calculate button. Here is how the Convective Mass Transfer Coefficient calculation can be explained with given input values -> 0.45 = 9/(40-20).
