Simple Calculation Breakdown

Plain-language explanation of how the current sizing output is produced.

Step 1
Calculate required flow
Required flow uses: rainfall × area ÷ 3600. Enter rainfall and area to compute it.
Step 2
Check selected product family
The tool checks active products in the chosen family (Vortex, Filter, or both) against the required flow.
Step 3
Pick smallest product that meets flow
It picks the smallest product whose typical flow is equal to or above the required flow. If none match, it shows a fallback suggestion.

Mode = FLOW (basis = catchment area)

Required flow formula: (rainfall × area) ÷ 3600

Waiting: enter rainfall and catchment area.
