Question 1

What is ACFM?

Accepted Answer

Actual Cubic Feet per Minute—air flow at actual pressure and temperature conditions, not standardized.

Question 2

How do you convert ACFM to LPM?

Accepted Answer

Multiply ACFM by 28.3168. Example: 10 ACFM = 283.2 LPM. Note: ACFM depends on actual conditions.

Question 3

How does pipe diameter affect flow rate?

Accepted Answer

Flow rate is proportional to the square of diameter. Doubling pipe diameter quadruples potential flow rate at the same pressure.

Question 4

What's the difference between volume and mass flow rate?

Accepted Answer

Volume flow (gallons/min) ignores fluid density. Mass flow (kg/s) accounts for density, important when density changes with temperature or pressure.
