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 Mass Diffusing Rate through Solid Boundary Sphere?
Mass Diffusing Rate through Solid Boundary Sphere calculator uses Mass Diffusing Rate = (4*pi*Inner Radius*Outer Radius*Diffusion Coefficient*(Mass Concentration of Component A in Mixture 1-Mass Concentration of Component A in Mixture 2))/(Outer Radius-Inner Radius) to calculate the Mass Diffusing Rate, Mass Diffusing Rate through Solid Boundary Sphere is defined as amount of particles diffusing through Solid Boundary Sphere per unit time. Mass Diffusing Rate is denoted by m_{a} symbol.
How to calculate Mass Diffusing Rate through Solid Boundary Sphere using this online calculator? To use this online calculator for Mass Diffusing Rate through Solid Boundary Sphere, enter Inner Radius (r_{inner}), Outer Radius (r_{outer}), Diffusion Coefficient (D_{ab}), Mass Concentration of Component A in Mixture 1 (ρ_{a1}) & Mass Concentration of Component A in Mixture 2 (ρ_{a2}) and hit the calculate button. Here is how the Mass Diffusing Rate through Solid Boundary Sphere calculation can be explained with given input values -> 3518.584 = (4*pi*5*7*0.8*(40-20))/(7-5).
