Determine the ceramic tile needed for the Real Estate Office in Appendix E. Using the labor rates from Problem 7-31 and the crew rate for the finish crew from Problem 7-32 determine the cost install the ceramic tile. From Problem 34, the area of the floor is 76 square feet and the perimeter of the rooms with tile is 60?3??. Deduct the doors from the wall.
What will be an ideal response?
Length = 60?3?? – 3 ea × 3 ? = 51?3??
Area of tile = 51?3?? × 4? = 205 sf

Calculate the ultimate BOD of the mixed river and sewerage stream.
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?
