Formula and methodology
Formula: Mean velocity=flow rate/circular area=4×flow rate/(π×diameter²).
The mean speed follows from distributing volumetric flow across the circular cross-sectional area.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Volumetric flow rate — m³/s; minimum -1000000000000; maximum 1000000000000
- Inside diameter — m; minimum 1.0E-6; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Volumetric flow rate | 0.01 |
| Inside diameter | 0.1 |
Mean velocity ≈1.273 m/s.
Assumptions and limits
- The entered diameter is the unobstructed circular inside diameter.
- Flow rate and velocity share a direction convention and the mean profile is used.
- Compressibility, roughness, swirl, pulsation, and noncircular corrections are not modeled.
