Vacuum - Flow Measurement
Measure air volume flow in vacuum. Convert between standard volume flow (scfm/nl/s) and actual volume flow (acfm/al/s) using pressure and temperature.
Vacuum - Flow Measurement Calculator
Convert standard volume flow to actual volume flow in vacuum conditions.
Use the formula:
qa = qs (29.92 / p) ((t + 460) / 520)
Where:
- qa = actual volume flow (acfm)
- qs = standard volume flow (scfm)
- p = actual pressure (in Hg absolute)
- t = temperature (°F)
