Formula and methodology
Formula: flow L/min=volume litres/(seconds/60); flow m³/h=flow L/min×0.06.
A timed-volume measurement gives an average flow rate. Pressure, pipe size, elevation, valve position, pulsation, and instrument uncertainty are not inferred.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Collected volume (L) — minimum 1.0E-6; maximum 100000000
- Collection time (seconds) — minimum 1.0E-6; maximum 100000000
Worked example
| Input | Value |
|---|---|
| Collected volume (L) | 20 |
| Collection time (seconds) | 30 |
Flow=40 L/min=2.4 m³/h.
Assumptions and limits
- Volume is measured in litres and time in seconds.
- Flow is reasonably steady during the collection interval.
- The result is an observed average, not a design capacity or water-quality assessment.
