reactive chemical disposed of by dilution in a river dissipates at a uniform rate of 0.15 mg/l A per hour. The waste discharge is 7 million gallons per day containing 35 mg/l, while the stream has zero concentration with a flow above the sewer outfall of 102 ft/s. If the mean velocity in the river is 0.8 ft/s, calculate the distance downstream that the chemical residual persists.
