4. A city discharges 100 cumecs of sewage into a river, which isfully saturated with oxygen and flowing at the rate of 1500 cumecs during itslean days with a velocity of 0.1 m/sec. The 5-days BOD of sewage at the giventemperature is 280 mgll. Find when and where the critical D.O. deficit willoccur in the downstream portion of the river, and what is its amount. Assumecoefficient of purification of the stream (f) as 4.0, and coefficient of de-oxygenation (K) as 0.1.
