Propane, stored in liquid form within a tank, exerts a variable force against the container walls depending primarily on temperature. A standard propane tank at 70F (21C) typically exhibits approximately 100-150 pounds per square inch (psi). This figure can fluctuate considerably with changes in ambient temperature; colder environments lead to lower pressures, while warmer conditions cause higher pressures. For instance, a tank at 0F (-18C) might register around 20 psi, whereas a tank at 100F (38C) could reach pressures exceeding 200 psi. The tank is designed to safely contain these fluctuating pressures within a specific range.
Understanding the internal forces within a propane tank is essential for safe handling and usage. Proper pressure maintenance ensures consistent fuel delivery to appliances and prevents potentially hazardous situations. Historically, the development of robust pressure vessels allowed for the safe storage and transport of propane, facilitating its widespread adoption as a fuel source. This knowledge contributes to effective leak detection, optimal appliance performance, and adherence to safety regulations. Ignoring pressure dynamics can lead to malfunctioning equipment or, in extreme cases, tank rupture.
