A1kgmass of some solute is deposited at the center of a square shallow bas in. The solute is instantly mixed of the vertical, and thus it diffuses only in the horizontal direction. If the basin is 1mdeep and each side is 1mlong, compute the concentration of the resulting solute slug at t=600s. Assume a “diffusion” coefficient that is equal to 0.025m2/s.
