What is the specific gravity of liquid propane compared to an equal volume of water?

The specific gravity of a substance is a comparison of its density to the density of water. In the case of liquid propane, its specific gravity is approximately 0.51, meaning that it is less dense than water. This indicates that if equal volumes of propane and water were measured, the propane would weigh less than the water. Therefore, when considering any applications or safety protocols related to propane, understanding this specific gravity is crucial, especially in contexts where the behavior of propane in relation to water is important, such as in leaks or spills.

This information is essential for handling and storage practices in the field, as lower specific gravity means propane will rise in air as it vaporizes, but can also lead to formations of flammable vapor clouds if it escapes into the atmosphere. Being aware of the specific gravity provides insight into the physical behavior of propane in relation to environmental factors and is vital in ensuring safety in operations involving this substance.
