Use the Vacuum Hose Diameter Calculator to estimate hose ID required for target evacuation flow/time. The calculator uses Vacuum line actual flow, Length, Mean absolute pressure, Allowable pressure loss and Air temperature and reports recommended id.
Read the result in the context of the selected units and pressure basis. For this tool, the primary outputs are recommended id. Change one input at a time when comparing scenarios so the effect of each variable remains clear.
PneumaForge applies this verified method: Iterative gas-line sizing with absolute sub-atmospheric pressure and Darcy/local losses; solve minimum ID meeting loss/velocity target. The functional engine is shared with related tools in the vacuum-line family, while this page solves the specific intent represented by vacuum hose diameter calculator.
Iterative gas-line sizing with absolute sub-atmospheric pressure and Darcy/local losses; solve minimum ID meeting loss/velocity target.Reproducible example: start with the calculator's default values (Vacuum line actual flow = 500; Length = 10; Mean absolute pressure = 0.5; Allowable pressure loss = 0.05) and calculate the result. Then change the variable most relevant to your application and compare the new recommended id against the baseline.

It is designed to estimate hose ID required for target evacuation flow/time. The reported outputs are recommended id.
The calculator uses Vacuum line actual flow, Length, Mean absolute pressure, Allowable pressure loss and Air temperature. Only use values that represent the same operating condition or design case.
The calculation follows: Iterative gas-line sizing with absolute sub-atmospheric pressure and Darcy/local losses; solve minimum ID meeting loss/velocity target. The page also states the assumptions that define where the method is valid.

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.
