Gutter And Downpipe Sizing Calculator
Gutter And Downpipe Sizing: a planned Super Calculator tool. Covers roof area (m2 or sq ft). Stub page while the tool and its worked example are prepared.
Gutter And Downpipe Sizing Calculator is a planned calculator in the home and energy section of Super Calculator, covering home and garden.
What this calculator will compute
Inputs: roof area (m2 or sq ft), roof pitch (deg), rainfall intensity (mm/h or in/h), gutter profile (label) and downpipe diameter (mm).
Outputs: design flow (l/s), required gutter size (label), downpipe count (n) and spacing (m).
Formula, recorded as scope and not yet verified against a primary source: Design flow equals effective roof catchment area times the design rainfall intensity for the location and return period; gutter and downpipe capacity are then selected from standard hydraulic capacity tables. Rainfall intensity is a local meteorological figure, not a constant.
