When determining sizing for gaseous substances, what specific gravity is assumed for propane?

• A. 1.0
• B. 1.5
• C. 1.8
• D. 2.0

Answer: (B)

When determining the specific gravity of propane, it is important to understand that specific gravity is a ratio that compares the density of a substance to the density of a reference substance, typically air or water. For gaseous substances, the reference is usually air, which has a specific gravity of 1.0 under standard conditions. Propane, when compared to air, has a specific gravity of about 1.5. This means that propane is approximately 1.5 times heavier than air. This value is significant for applications involving propane as it affects how propane behaves in the atmosphere, particularly with regards to ventilation, dispersion, and potential hazards related to leaks. Understanding the correct specific gravity of propane is vital for professionals in heating and gas applications to ensure safety and proper system design. Using the accurate value of 1.5 allows technicians and engineers to make informed decisions about appliance installation, gas line sizing, and the overall management of propane systems.
