A lake of 18 x 106 m² retains water from a stream and a sewage outfall before streaming it out. The inflow from the stream discharges at 8.0 m³s¹ and its pollutant concentration is 15.0 mg/L. The sewage outlet has a flow rate of 1.5 m³s¹ with pollutant concentration of 100 mg/L. Compute the steady-state pollutant concentration assuming that complete mixing occurs in the lake and the decay rate coefficient of the pollutant in the stream and the lake is 0.40/day.
