Compressed-air calculator
Internal volume of a compressed-air system
The system’s internal volume (piping and receivers) sets its inertia: it cushions demand peaks and underpins several measurements, including the flow test.
Add up your pipe runs and receivers to obtain the total system volume.
Total system volume
Cumulative internal volume: piping + receivers (2:1 elliptical heads).
Piping

Receivers
| # | Diameter | Length | Manual volume | m³ | ft³ | gal |

Receivers: cylinder + 2:1 elliptical heads, rounded to the nearest standard size; a manual volume takes precedence when entered.
