What does Reid Vapor Pressure measure?

Reid Vapor Pressure (RVP) measures the amount of flammable vapors given off by a liquid at a specified temperature, typically at 100°F (37.8°C). It reflects how easily a liquid can vaporize, which is essential for understanding the volatility of fuels and other liquids. High Reid Vapor Pressure indicates that a liquid readily produces vapors, which can contribute to flammability and explosion risks in specific environments, such as during storage and transportation.

This measurement is particularly important in the petroleum industry, as it helps in assessing the safety and handling of fuels. The characteristics of the vapors, including their flammability, provide crucial information for developing safety protocols and regulations to minimize hazards associated with volatile substances.
