Property is being transported through a fluid at steady state through a constant cross-sectional area. At point 1, the concentration (f₁) is 1.0 x 10⁻² amount of property/m², and at point 2 at a distance of 'd' meters away, the concentration (f₂) is 5.0 x 10⁻² amount of property/m².
The diffusivity depends on concentration as follows.
a) Determine the integrated equation for the flux in terms of time (t) and concentration at point 2 (f₂).
b) Calculate the flux.
c) Calculate the concentration at z = 1.0.
