Calculate the peak flow rate (in m3 /s) at the point of analysis which is marked in the map with a "red star" for a 2?year storm, using the Rational Method.

The following information is given:

Area 1 = 2.2 ha, assumed inlet time is 10 min, land use is shown in figure, assume 60% grass area and 40% paved/hard surface.

Area 2 = 1.75 Ha, assumed inlet time is 15 min, land use is shown in figure, assume suburban residential

Area 3 = 3.1 Ha, assumed inlet time is 20 min, land use is shown in figure, assume suburban residential

Area 4 = 0.4 Ha, assumed inlet time is 5 min, land use is shown in figure, assume paved with asphalt. Distance 120m.
