Calculate the ultimate BOD of the river, assuming kL = 0.20 day–1.
The Ganges River, shown in Figure 4.66, has an annual average flow rate of 12,105 m3/s. The average temperature of the Ganges River was reported to be 24.6ºC. The Ganges has become contaminated with raw sewerage and industrial waste so that the dissolved oxygen in the river upstream of sewerage discharges is 4.6 mg/L. Suppose that the raw sewerage that is untreated flows into the Ganges at a rate of 460 m3/s, the temperature is 25ºC, and the dissolved oxygen in the sewerage stream is completely depleted (i.e. DO = 0). How would you develop a plan for improving water quality in the Ganges River?
Suppose the following data was collected to estimated the five-day BOD in the river and sewerage water:

Which one of the following troubleshooting techniques is NOT useful for sequencer problems?
A) When troubleshooting a sequencer problem with a large database having many elements, start with just a small data set. B) If an SQO instruction is used with a timed input, then replace the timed input with a manual switch or forced input instruction to manually step through the sequencer file while all the sequencer outputs and machine actions are verified. C) Verify the instruction parameters, especially the length value. D) In applications where the sequencer instruction is false during the first PLC scan, verify the 0 position was included in the length value.
