4) In situations where the molecular diffusion component of dispersion is negligible relative to the mechanical dispersion component, the 1-dimensional Ogata-Banks equation becomes: a. Using this equation, generate breakthrough curves (all on one plot, plot C/Co) for the column described in Question 3 assuming dispersion coefficients (m2/hr) of i) 0.001 ii) 0.01 iii) 0.1. Show your work and all of your back-up. b. What impact does an increasing dispersion coefficient have on the breakthrough curves? c. Does the dispersion coefficient have any impact on the time to reach C/Co =0.5? Why or why not
