Fick's second law calculator
WebFick’s second law is a statement of the conservation of matter (with no allowance for production). 2. The solution to the diffusion equation for a point source of strength M (per unit length) located at the origin x =0 in a one-dimensional system extending from x = −∞ to x = ∞ is M x2 c(x,t)= √ exp (3) 4πDt − 4Dt WebAbstract. In this chapter, Fick’s laws of diffusion are introduced. The second law is derived using the first law and the mass conservation. Solutions for the second law considering a constant ...
