1) A biofilm is a layer-like aggregation of microscopic animals, plant or bacteria attached to a solid surface. Assume such a biofilm where the reactant is consumed Bulk fluid only at the solid surface, maintaining a particular value of surface concentration. Calculate the steady-state reactant flux into a biofilm of thickness 0.01 cm, if the diffusivity of the reactant in the biofilm is 0.8 cm²/day. Assume the reactant concentration in the bulk fluid to be uniform at 3.2 mg/liter. At the surface, reactant concentration is 0.25 mg/liter. Biofilm Surface
