Use the Compressed Air Pipe Sizing Calculator to select pipe ID for required flow and allowable pressure drop. The calculator uses Reference air flow, Length, Upstream absolute pressure, Allowable pressure drop and Fittings equivalent length and reports required id/nominal size; velocity; estimated drop.
Read the result in the context of the selected units and pressure basis. For this tool, the primary outputs are required id/nominal size; velocity; estimated drop. Change one input at a time when comparing scenarios so the effect of each variable remains clear.
PneumaForge applies this verified method: Validated compressed-air pipe pressure-loss relation / segment iteration. The functional engine is shared with related tools in the pipe-network family, while this page solves the specific intent represented by compressed air pipe sizing calculator.
Validated compressed-air pipe pressure-loss relation / segment iterationReproducible example: start with the calculator's default values (Reference air flow = 500; Length = 10; Upstream absolute pressure = 7.01325; Allowable pressure drop = 0.2) and calculate the result. Then change the variable most relevant to your application and compare the new required id/nominal size; velocity; estimated drop against the baseline.
Intended for conventional compressed-air distribution. Add equivalent straight length for fittings when available. Validate velocity and pressure-drop budget.
It is designed to select pipe ID for required flow and allowable pressure drop. The reported outputs are required id/nominal size; velocity; estimated drop.
The calculator uses Reference air flow, Length, Upstream absolute pressure, Allowable pressure drop and Fittings equivalent length. Only use values that represent the same operating condition or design case.
The calculation follows: Validated compressed-air pipe pressure-loss relation / segment iteration. The page also states the assumptions that define where the method is valid.
Intended for conventional compressed-air distribution. Add equivalent straight length for fittings when available. Validate velocity and pressure-drop budget.
Yes. PneumaForge converts supported units through canonical engineering units. For compressed-air reference flows and pressure bases, the reference pressure and temperature must also remain consistent.
