3. A wastewater treatment plant discharges its effluent (flow of 4 MGD ((1 gal = 0.003785 m³), DO of 5 mg/L, BOD5 of 20 mg/l and T of 25°C into a river (flow of 50,000 m³/d, DO of 7.5 mg/L, BOD5 of 4 mg/L and T of 15°C). The deoxygenation coefficient is 0.28/day. Estimate the T, DO, BOD5, and BODu, right after mixing.
