The analytical solution for the concentration of a compound in 1-d for a pulse input of mass (based on Fick's 2nd law) is given as: MC(x,t)=2Dlt1exp(4Dltx2) where D1= longitudinal dispersion (L2T1) t=time(T)x=length(L) Plot C(x,t)/M for a range of x=5 to +5 for (D1t)=0.1,0.5,1.0,2.0, and 5.0. There will be 5 series (of length which is the independent variable and C/M which is the dependent variable) but plot in the same graph. Units of x,D1, and t are such that Dltx2 is nondimensional. Clearly label your axes
