In a natural gas system, a specific gravity of 0.60 indicates what about the gas?

In a natural gas system, a specific gravity of 0.60 indicates that the gas is lighter than air. When the specific gravity of a gas is less than 1.0, it means that the gas is less dense than air, which has a specific gravity of approximately 1.0. In this case, natural gas with a specific gravity of 0.60 is significantly lighter than air.

This characteristic is important for safety and operational considerations, as lighter gases tend to rise and disperse quickly in the atmosphere, reducing the risk of buildup and potential hazards associated with gas leaks. Hence, the correct understanding of specific gravity in the context of natural gas significantly aids in effectively managing its use and safety in various applications.
