1. A lagoon is to be designed to accommodate an input flow of 0.10 m3/s of non-conservative pollutant with concentration 30.0 mg/L and reaction rate 0.20/day. The effluent from the lagoon must have pollutant concentration of less than 10.0 mg/L. Assuming complete mixing, how large must the lagoon be?
