2 (a) A city on with 1.5 lakhs population procedure at the rate of 150 lped and the sewage treatment plant effluent has a BOD5 of 25 mg/l at 20°C and a D.O of 1.5mg/l. The effluent is discharged into a stream having a flow of 5m3 sec at a velocity of 32cm/sec the stream temperature remains unchanged at 20°C after trhe discharge of the effluent , the stream which is 85% saturated with D.O has a BODS of 1.0 mg/l a self purification factor f=2.25 at 20°C with K1=0.1/day. The saturation D.O at 20° C is 8.2 mg/l. Assume data necessary. Determine
