Q 3-B) The waste stream has dissolved oxygen concentration of 3.7 mg/l, flow rate 0.9 m3/s, temperature of 28 Oc, and an ultimate biochemical oxygen demand of 47 mg/l. The stream water is running at 2.7 m/s at a saturated dissolved oxygen concentration, temperature of 19 Oc, and an ultimate BOD of 13.8 mg/l. Calculate the DO concentration 49.3 km down stream.
