What is the specific gravity range of liquefied petroleum (LP) gas?

The specific gravity of liquefied petroleum (LP) gas typically falls within the range of 1.0 to 1.5. Specific gravity is a dimensionless number that compares the density of a substance to the density of water. For LP gas, which includes propane and butane, the specific gravity is less than that of air (about 1.0), which means LP gas is generally lighter than air.

This characteristic is important for safety and handling since it indicates how LP gas will behave in the event of a leak; it will rise and disperse quickly into the atmosphere if released. The range mentioned aligns with typical values found in technical references regarding LP gas properties. Having this understanding is crucial for HVAC professionals, as it informs how they design, install, and maintain systems using LP gas, ensuring both efficiency and safety in its operation.
