Determine the smallest required concrete round pipe and rectangular box sewers for Q = 100, 150, 200,

Question:

Determine the smallest required concrete round pipe and rectangular box sewers for Q = 100, 150, 200, and 250 cfs, S = .005 ft / ft, and n = 0.013 using Eq. (9 - 3). Tabulate results and compare capacities and areas of the round to box sewers. Use standard increment sizes of 0.5 ft for round pipe and 1.0 ft for box sewer.
