What should be the minimum size of a gas line for effective flow?

• A. 1 inch
• B. 3/4 inch
• C. 2 inches
• D. 1.5 inches

Answer: (B)

The minimum size of a gas line is crucial for ensuring effective flow, especially in residential and commercial applications. A 3/4 inch diameter gas line is often considered the standard minimum for many installations. This size strikes a balance between adequate gas flow for heating appliances and minimizing pressure drop, which can occur with smaller lines. Larger gas lines, such as 1 inch or above, may be necessary for larger volume requirements or longer runs to ensure adequate pressure reaches the appliances. However, if the demand is not high, opting for a larger size may not be efficient or necessary. Additionally, using a gas line that is too small can lead to inadequate supply, resulting in problems with appliance performance. Thus, selecting a 3/4 inch line as the minimum helps ensure that gas flows efficiently for common applications without unnecessary expense on larger lines that may not be needed for lower consumption scenarios.
