A large stream has a re-oxygenation constant of 0.4 per day. At a velocity of 0.90 m/s and at the point at which an organic pollutant is discharged, it is saturated with oxygen at 9.2 mg/L (D-0). Below the outfall, the ultimate demand for oxygen is found to be 20 mg/L and the de- oxygenation constant is 0.2 per day. What be the DO at 50 km downstream?
