11.11. A combination inlet consists of a 3-m-long curb inlet and a 0.6-m by 1.2-m reticuline grate inlet adjacent to the downstream 1.2 m of the curb opening. The gutter section has a width of 0.6 m, a longitudinal slope of 1.5%, a cross slope of 3.5%, and a gutter depression of 30 mm. The roadway pavement consists of rough asphalt. For a flow rate of 0.09 m /s in the gutter, calculate the inter- ception capacity of the inlet.
