How to Calculate Non-steady state diffusion?
Non-steady state diffusion calculator uses Concentration at x Distance = Initial Concentration+(Surface concentration-Initial Concentration)*(1-erf(Distance/(2*sqrt(Diffusion Coefficient*Diffusion Time)))) to calculate the Concentration at x Distance, Non-steady state diffusion represents the time dependent diffusion of species, a transient diffusion state. Concentration at x Distance is denoted by C_{x} symbol.
How to calculate Non-steady state diffusion using this online calculator? To use this online calculator for Non-steady state diffusion, enter Initial Concentration (C_{0}), Surface concentration (C_{s}), Distance (d), Diffusion Coefficient (D) & Diffusion Time (t) and hit the calculate button. Here is how the Non-steady state diffusion calculation can be explained with given input values -> 0.701888 = 300+(0.7-300)*(1-erf(0.01/(2*sqrt(800*1000)))).
