Question 1

What is MMSCFD?

Accepted Answer

Million Standard Cubic Feet per Day—natural gas flow. 1 MMSCFD ≈ 327.74 L/s at standard conditions.

Question 2

Why does natural gas use standard conditions?

Accepted Answer

Gas volume varies with pressure and temperature. Standard conditions (60°F, 14.7 psi) allow fair comparison.

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.
