Formula and methodology
Formula: Internal volume = pi/4 x (outer diameter^2 - inner diameter^2) x length.
A straight hollow pipe is modeled as the difference between two coaxial cylinders. The result is internal geometric capacity and does not calculate pressure rating, flow rate, fittings, or usable working volume.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Outer diameter — m; minimum 1.0E-6; maximum 1000000
- Inner diameter — m; minimum 0; maximum 1000000
- Pipe length — m; minimum 1.0E-6; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Outer diameter | 0.1 |
| Inner diameter | 0.08 |
| Pipe length | 1 |
Internal pipe volume is 0.00282743 m^3.
Assumptions and limits
- Both diameters and length use the same length unit.
- Inner diameter is less than outer diameter.
- The pipe is straight, uniform, and circular with no fittings or fluid compressibility effects.
