5. (20 pts) Water flows into and out of a well-mixed, 1.6x10% L tank at a rate of 1000 L/min. The dissolved oxygen (DO) concentration in the influent is 1.0 mg/L. In the tank, bacteria use the oxygen for metabolism in proportion to the amount of oxygen present; that is, they use it at a rate k= 2x10 min! Oxygen is dissolving into the water at a rate proportional to the degree of under saturation; that is, at a rate given by k a = 4x10 min'. If the saturation concentration of DO is 10 mg/L, find the steady-state concentration of DO.
