For the storm sewer system shown below, determine the required diameter of the sewers; extended from inlet No.1 to inlet No.2 (L-60m), extended from inlet No.2 to inlet No.3 (L=80m), and outgoing from inlet No.3. Assume the flow velocity in sewers at full flow condition is 0.8m/sec and Manning roughness coefficient is 0.013. Inlet No. 1 2 3 Drainage area (m²) 10000 15000 20000 Overland flow time (min) 5 6 12 Runoff coefficient 0.2 0.3 0.4
