The concentration of a pollutant along a quiescent water-containing tube is shown in Figure 4-23. The diffusion coefficient for this pollutant in water is equal to 10^-5 cm² s^-1.

(a) What is the initial pollutant flux density in the x-direction at the following locations: x - 0.5, 1.5, 2.5, 3.5, and 4.5?

(b) If the diameter of the tube is 3 cm, what is the Initial flux of pollutant mass in the x-direction at the same locations?
