What is the expansion ratio of liquid propane to vapor?

The expansion ratio of liquid propane to vapor is 270:1. This means that when liquid propane vaporizes, it expands to 270 times its volume in the gaseous state. Understanding this ratio is essential for safety and efficiency in the storage and transportation of propane, as it highlights the significant difference in density between the liquid and vapor forms.

In practical terms, this means that a relatively small amount of liquid propane can produce a large volume of gas when it evaporates. Such knowledge is important in handling propane safely in various applications, including heating and power generation, as well as in ensuring that systems designed to contain propane account for this significant expansion upon vaporization.
