What is Reid Vapor Pressure?

A exerted by liquid cargo on the sides of a tank
B a measurement of the amount of flammable vapors given off by a liquid at a certain temperature
C exerted by liquid cargo on a cargo hose body
D the lowest temperature and pressure that will cause a flammable liquid to give off vapors
AI Explanation

The correct answer is B) a measurement of the amount of flammable vapors given off by a liquid at a certain temperature. Reid Vapor Pressure (RVP) is a measurement of the vapor pressure of a liquid fuel at 100°F (37.8°C). It is used to determine the volatility and flammability of the fuel, which is an important safety consideration for the handling and storage of flammable liquids. The higher the RVP, the more easily the liquid will vaporize and form flammable vapors. The other answer choices are incorrect because they do not accurately describe the definition of Reid Vapor Pressure. Option A refers to hydrostatic pressure, option C refers to pressure in a cargo hose, and option D describes the flash point, which is a different property than RVP.
