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
1) The value of initial D.O deficit for the stream just below the point of plant discharge.
2) The distance downstream of the river at which the D.O is minimum .
3) The magnitude of Dc
