Calculation
A = Q / v
Larger area lowers velocity, noise and pressure loss.
Q = v·A
Pipe area from flow and velocity
Larger area lowers velocity, noise and pressure loss.

Result
Select a target and calculate.
Understand the inputs
- Open area A — Internal flow area.
- Target flow Q — Design flow.
- Allowable velocity v — Limit for noise, erosion and pressure loss.
Example
60 l/min at 1 m/s needs 1,000 mm².
Assumptions and limits
Full circular pipe; fitting losses are excluded.
