Question
Please help, the area runoff coefficient and inlet time for each sub catchment shown in the table.
A 27-acre drainage basin comprising of seven sub-catchments is shown in Fig. 1. Determine the design flows (Q) entering manholes A, B, C, and E in cfs for a 5 year return period. The area, runoff coefficient and inlet time for each sub-catchment is shown in Table 1; the length and slope for each pipe in Table 2. Use the rainfall intensity equation 12070.175 Ta+27 where i is the rainfall intensity in inches/hr, Tis the return period and T. is the duration in minutes.
