At 130°F, what is the vapor pressure of propane in PSIG?

The vapor pressure of propane at a specific temperature is a crucial characteristic in various applications, including dispensing and storage. When examining the question, the focus is on determining the accurate vapor pressure of propane at 130°F, which is known in the field.

At 130°F, the vapor pressure of propane is well-documented in thermal properties tables and can be determined through reliable sources. The value indicates how much pressure the gas exerts when in equilibrium with its liquid phase at that temperature. This property is essential for understanding how propane behaves in storage tanks and dispensers, influencing safety measures and equipment design.

The value of 287 PSIG aligns with these reliable data sources, confirming its accuracy as the vapor pressure at 130°F. Thus, this makes it the correct answer for this question, reflecting an established understanding of propane's physical properties and its implications in practice.

If accuracy is essential for operations involving propane, such as ensuring appropriate pressure settings for dispensing equipment, knowing these precise values can help avoid potential hazards related to overpressure or underpressure conditions.
