>68 KPa and <75 kPa at 100F (37.8C)
Reid vapor pressure (RVP) of gasoline is the vapor pressure at 100°F.

Under the ASTM Method D 323 (Reid vapour pressure), it is the absolute vapour pressure exerted by a liquid at 100°F. The higher this value, the more volatile the sample and the more readily it will evaporate. Unlike distillation data, vapour pressure provides a single value that reflects the combined effect of the individual vapour pressure of the different petroleum fractions in accordance with their mole ratios. It is thus possible for two wholly different products to exhibit the same vapour pressure at the same temperature - provided the cumulative pressures exerted by the fractions are the same. A narrow-cut distillate, for example, may exhibit the same vapour pressure as that of a dumbbell blend, where the effect of heavy fractions is counterbalanced by that of the lighter ones. In conjunction with other volatility data. Reid vapour pressure plays a role in the prediction of gasoline performance.
There isn't RVP condensate. Condensate is the hydrocarbon liquid that comes out of the ground at gas wells. RVP is a measure of the amount of "light ends" in the liquid. RVP is roughly a measure of how light or heavy oil is, or how long the carbon chains are.
The typical Reid vapor pressure range in naphtha is between 2 to 15 pounds per square inch (psi). Reid vapor pressure is a measure of the vapor pressure of volatile petroleum products, including naphtha. High Reid vapor pressure indicates increased volatility.
The Reid vapor pressure of LPG (liquefied petroleum gas) typically ranges from 100 to 200 psi (pounds per square inch) at 100°F. Reid vapor pressure is a measure of the volatility of a fuel, indicating its tendency to evaporate.
The volatility of gasoline.
The optimum Reid Vapour Pressure (RVP) for transporting crude oil typically ranges between 8 to 12 psi, depending on the specific characteristics of the crude and regulatory requirements. Maintaining this range helps minimize the risk of vaporization and ensures safe transport while reducing emissions. Higher RVP values can lead to increased volatility and potential handling issues, while lower values may indicate heavier, less desirable crude. Ultimately, the target RVP should balance safety, regulatory compliance, and the physical properties of the crude oil.
Chilling the sample in the Reid vapor pressure test helps to reduce the vapor pressure of the volatile components in the sample, making it easier to measure accurately. This allows for more precise determination of the vapor pressure under controlled conditions.
its just under 0.5 pounds.
The amount of light components in the oil affect the reid vapor vapor pressure. In petroleum products such as gasoline, the amount of butane in the gasoline blend has a strong affect on the Reid Vapor Pressure. To reduce RVP more stripping steam can be added to the product strippers. The fractionation in the debutanizer might also need to be adjusted to affect the RVP.
