Chapter 11, Problem 27P
As described in Sec. PT3.1.2,
0=Dd2cdx2−Udcdx−kc
Where c= concentration, t= time, x= distance, D= diffusion coefficient, U= fluid velocity, and k=a first-order decay rate. Convert this differential equation to an equivalent system of simultaneous algebraic equations. Given D=2, U=1, k=0.2, c(0)=80 and c(10)=20, solve these equations from x=0 to 10 with Δx=2, and develop a plot of concentration versus distance.
