Question 1

What is NCFM?

Accepted Answer

Normal Cubic Feet per Minute—air flow at normal conditions (0°C, 1 atm). Used in gas flow standardization.

Question 2

How do you convert NCFM to LPM?

Accepted Answer

Multiply by 28.3168. Example: 10 NCFM = 283.2 LPM (at normal 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.
