What is the expansion ratio of liquid propane to its vapor state?

The expansion ratio of liquid propane to its vapor state is approximately 270:1. This ratio indicates that one volume of liquid propane converts to about 270 volumes of propane gas when it vaporizes. This significant expansion is critical to understand in practices involving storage, handling, and safety of propane gas, as it highlights the potential for rapid pressure increases if liquid propane is allowed to vaporize in a confined space.

Understanding this expansion ratio aids in designing proper storage containers, ensuring safety measures are in place to handle the vapor release, and performing accurate calculations for fuel usage in various applications. It is essential for professionals in the LP gas industry to be aware of this conversion factor to prevent accidents and to ensure efficient system designs.
