Awastewater treatment plant discharges 1.0 m3/s of effluent having an ultimate bod of 40.0 mg/ l into a stream flowingat 10.0 m3/s. just upstream from the discharge point, the stream has an ultimate bod of 3.0 mg/l the deoxygenationconstant kd is estimated at 0.22/day.(a) assuming complete and instantaneous mixing. find the ultimate bod of the mixture of waste and river just downstreamfrom the outfall.(b) assuming a constant cross-sectional area for the stream equal to 55 m2, what ultimate bod would you expect to find ata point 10.000 m downstream?
