When installing our high capacity gutters there is no requirement with the exception of the small half rounds to fix to falls.
Both the velocity and flow rate in a gutter vary.

Use 8 3 ft s the splash over velocity for the grate used with the sw 547 sw 548 and sw 549.
R f cannot be greater than 1 00.
The time of flow can be estimated by use of an average velocity obtained by integration of the manning s equation for the gutter section with respect to time.
Pay attention to locations where the roadway superelevation goes to zero when a tangent section goes to a curve.

Our revolutionary patented gutter flow system creates and maintains an open channel within your gutter so that they can catch and control all the rainwater from your roof.
The velocity in a gutter varies with the flow rate and the flow rate varies with the distance along the gutter i e.
