Assuming that the mixed oxygen deficit (Da) is zero and that the ultimate BOD (Lt) of the Manco Capac River above the wastewater outfall from Urcaguary is zero, calculate the amount of ultimate BOD (in kg/day) that can be discharged if the DO must be kept at 4.00 mg · L−1 at a point 8.05 km downstream. The stream deoxygenation rate (kd) is 1.80 /day at 12°C, and the reaeration rate (kr) is 2.20 /day at 12°C. The river temperature is 12°C. The river flow is 5.95 m^3/s with a speed of 0.300 m/s. The Urcaguary wastewater flow is 0.0130 m^3/s.
