The diversity factor accounts for what in gas piping design?

• A. Variability in gas usage among multiple appliances
• B. Variability in weather
• C. Variability in installation date
• D. Variability in piping color

Answer: (A)

Diversity factor reflects the fact that multiple gas-burning appliances rarely reach their maximum demand at the same time. In sizing piping and regulators, engineers use the expected simultaneous demand, which is typically less than the sum of each appliance’s individual peak. This allows proper capacity without oversizing, ensuring safe, economical design while still meeting peak needs. Weather variation, installation date, or piping color don’t describe how demand varies across different appliances, so they aren’t the basis for this factor.
