3. Determine the smallest required concrete round pipe and rectangular box sewers for Q=100, 150, 200, and 250 cfs, S=0.005 ft/ft, and n=0.013 using Manning's Equation. Tabulate results and compare capacities and areas of the round and box sewers. Use standard increment sizes of 0.5 ft for round pipe and 1.0 ft for box sewers.

Question
Answer question 3. When solving this problem, keep in mind that a square is the most efficient type of rectangle (largest area for a given perimeter/smallest perimeter for a given area). Therefore, if you select a square box culvert, you will have only one unknown. Also, Goal Seek in Excel can be helpful for this one.
1. For a runoff volume of 125.6 m³, determine the depth of storage in a retention basin that has vertical
walls and a base area of 500 m².
2. A 6-ac basin is to be developed into 2 ac of commercial development (C=0.95) and 4 ac of park (C=0.2),
as shown below. Using the tabulated IDF information, what should be the design flow at the inlet?

4. Given the inlet below, with h=0.5 ft, W=1.5 ft, L=4.0 ft, and a gutter depression depth=0.33 ft, determine
what is the Q into the inlet if the depth of the storm water at the curb is 1.0 ft (i.e., there is 6 inches of
water depth above the standard curb height of 6 inches for a total depth at curb of 1.0 ft).
