7.1 Use the rational method to determine the peak RDII in the pipe segment down- stream of each inlet in the combined sewer shown in the schematic. The 10-yr storm in Figure 7.12 may be used to determine the rainfall intensity. Use the Hathaway equation to determine the time of concentration. Each pipe segment has a length of 300 ft and an average velocity of 4 ft/s.
