What is the specific gravity range of natural gas?

Natural gas is primarily composed of methane (CH4), which has a specific gravity that typically falls within the range of 0.60 to 0.65 when compared to air. Specific gravity is a measure of the density of a substance relative to the density of a reference substance, which in the case of gases is usually air. This means that natural gas is lighter than air, a critical characteristic for safety and ventilation considerations.

Understanding the specific gravity of natural gas is significant in various practical applications such as installation, leak detection, and safety inspections. Gas that has a lower specific gravity than air will rise, while heavier gases may accumulate in low areas, posing risks. Therefore, knowing that the specific gravity range of natural gas lies between 0.60 and 0.65 is vital for professionals working with gas systems to ensure they address any potential safety hazards effectively.
