Question

Wastewater from a mining township is discharged at the rate of 1 cubic metre per second into a stream flowing at 10 cubic metre per second. BOD of the waste water is 50 milligram per litre, whereas the BOD of the stream is 6.0 milligram per litre. The deoxygenation constant kd is 0.20 per day. If the stream can be assumed to flow at 0.3 metre per second, what may be the BOD at 2000 downstream?    ​

Answer 1

Answer:

The Elder Transcripts is a project that collects historically significant knowledge from the elders in the community. Much of the valuable information known by these individuals has not been written down anywhere, and as time passes these individuals pass away. With their passing so goes their knowledge and insight into the community's past. The urgency of this project can not be overstated. Many of the stories about people and events have been lost. However, there are still many stories to be told by many citizens.
