Question 1

How do you convert CFM to cubic meters per hour?

Accepted Answer

Multiply CFM by 1.699. Example: 500 CFM = 849.5 m³/h.

Question 2

Why convert CFM to m³/h?

Accepted Answer

CFM is US standard, m³/h is metric standard. International HVAC projects need both unit systems.

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.
