Pipe Sizing Calculations <br /> Pipes from CB's #17-27 were not sized based off of flows and capacities due to the size of the existing <br /> pipes where the connections will be made. <br /> From <br /> CB#7 to Apron 8 0.26 cfs @ 7.59%— 12"HDPE(Capacity=9.82 cfs) <br /> CB#13 to CB#12 0.27 cfs @ 0.49%— 10"PVC (Capacity= 1.53 cfs) <br /> CB#12 to CB#11 0.27 cfs @ 0.50%— 12" HDPE(Capacity=2.52 cfs) <br /> CB#11 to Apron 10 2.05 cfs @ 4.38%— 12" HDPE(Capacity=7.45 cfs) <br /> MH#6 to MH#5 0.00 cfs @ 2.94%— 12" HDPE(Capacity=6.11 cfs) <br /> MH#5 to CB#4 3.31 cfs @ 0.30%— 18" HDPE(Capacity=5.75 cfs) <br /> CB#4 to CB#3 7.19 cfs @ 0.30%—*24" HDPE(Capacity= 12.44 cfs) <br /> CB#3 to CB#2 8.75 cfs @ 0.30%—*24" HDPE(Capacity= 12.44 cfs) <br /> CB#2 to CB#12 9.40 cfs @ 0.30%—*24" HDPE(Capacity= 12.45 cfs) <br /> CB#1 to Apron 14 21.96 cfs @ 2.41%—* 30" HDPE(Capacity=35.13 cfs) <br /> Pipes are sized for a 10-YR Storm Event. Capacity is calculated using Mannings Equation with n=0.013. <br /> *See Attached HydroCAD report for More Details on Runoff and Pipe Sizing. <br />
