Flow rate calculator
Calculate the flow in a pipe from inner diameter and flow velocity.
Flow (l/min)

01
V̇ = A · v
Flow rate is the cross-sectional area times the flow velocity.
02
Cross-section
The area follows from the inner diameter via A = π·(d/2)².
03
Units
We show the result in l/min, l/s and m³/h — handy for any context.
Rough calculation, no warranty. Calculated inner cross-section, without friction losses.
