Web19 feb. 2024 · Gasoline fuel parameters such as vapor pressure (including Reid Vapor Pressure, RVP), refueling loss, OH reactivity in forming atmospheric ozone pollution, and other fuel characteristics were addressed. The assumptions made and model results were validated by comparison to measured fuel parameters from 9 unleaded gasoline fuels. Web6 jun. 2024 · The vapor pressure of water is the pressure at which the gas phase is in equilibrium with the liquid phase. The high surface tension of water (water "sticks" to itself, so it doesn't "want to" evaporate) means water has a low vapor pressure. An explanation of vapor pressure Sources/Usage: Public Domain. Reid vapor pressure (RVP) is a common measure of the volatility of gasoline and other petroleum products. It is defined as the absolute vapor pressure exerted by the vapor of the liquid and any dissolved gases/moisture at 37.8 °C (100 °F) as determined by the test method ASTM-D-323, which was first developed in … Meer weergeven • Crude oil assay • Gasoline volatility • Vapor pressure Meer weergeven • ASTM D323 - 06 Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method) • Reid Vapor Pressure Requirements for Ethanol Congressional Research Service • USA's Environmental Protection Agency (EPA) publication AP-42, Compilation of Air Pollutant Emissions.
