Document Summary
The cbod curve in the plot is calculated using cbod = l0e-kt . 101. 325 kpa) from appendix a of the textbook: the graph for dosat was almost a straight line since the values varied from 9. 06 to 9. 22. The dissolved oxygen values are the difference between dosat and. The graph initially begins at 7. 08 mg/l and drops down at. 20. 8 km to the lowest value and that point is called at critical deficit point: the dissolved oxygen value increases from that point to 7. 67 mg/l at 100 km. 7. 50 mg/l to 28. 54 mg/l and the concentration of do is decreased from 6. 35 mg/l to 5. 45mg/l: the changed can we observed when the two plots are compared to each other. I ironically, it is life in the form of plants and algae that grow uncontrolled due to fertilizer that leads to the masses of decaying plant matter.
