may have figured this out. if I convert the L in 2 L/m-s to m^3 I get .002 m^2/s. then if I take (.28 m^3/s)/(.002m^2/s) = 140m. so basically this is a right triangle with a hypotenuse of 2L/m-s and leg1 = .28m^3/s and leg2 = length. Any thoughts or further info is welcome.
A suburban street receives storm water runoff at rate of 2.0 L/m-s (on each side). The street has a slope of .8 percent and a cross slope of 2 percent; n = .013. If the street is 10 m wide and can be totally covered by water (depth = 0 at the midpoint), what is the max distance between inlets...
