What is the specific gravity of natural gas used in a 520-foot gas line installation?

The specific gravity of natural gas is a crucial parameter in gas line installations because it influences how gas behaves in various conditions. Specifically, the specific gravity of natural gas, when compared to air, is typically around 0.6. Understanding this value is important for various reasons, including the safe handling of natural gas, proper calculation for ventilation requirements, and the design of gas distribution systems.

In practical situations, natural gas has an average specific gravity ranging from about 0.55 to 0.65, with 0.60 being a common reference point. A specific gravity of 0.60 means that natural gas is lighter than air (which has a specific gravity of 1.0), making it rise and disperse quickly in the atmosphere if a leak occurs. This characteristic is vital in safety protocols and in ensuring that gas lines are designed to minimize risk.

The selected answer indicates a specific gravity of 0.60, aligning well with industry standards for natural gas, and reflects the expected behavior of gas within a typical gas line installation scenario. This understanding aids technicians in ensuring safe designs and appropriate responses to potential hazards associated with gas usage.
