What effects might there be on human health and recreation? Note that the Ganges is a source of drinking water, water for washing, and has a spiritual significance to the surrounding population.
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? What will be an ideal response?

Dickinson, a large oil and gas drilling and operating corporation, has invested over the past 6 years in the installation and operation of a FOUNDATION Fieldbus H1 (FF H1) system developed by Pepperl+Fuchs of Germany. A project engineer has collected information on annual net cash flow increases (?NCF) generated by the FF H1 system and the annual investments made by Dickinson in the system. At an interest rate of 10% per year, determine the PI of this endeavor. Has it proven to be economically worthwhile? (Note: Problem 9.54 explores the fieldbus implementation further using a spreadsheet.)
