Reid vapor pressure (RVP) is a common measure of the volatility of gasoline and other petroleum products. [1] 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 1930 [2] and has been revised several times (the latest version is ASTM D323 ...
True vapor pressure (TVP) is a common measure of the volatility of petroleum distillate fuels. It is defined as the equilibrium partial pressure exerted by a volatile organic liquid as a function of temperature as determined by the test method ASTM D 2879.
The higher the gasoline volatility (the higher the RVP), the easier it is to evaporate. The conversion between the two fuels occurs twice a year, once in autumn (winter mix) and the other in spring (summer mix). The winter blended fuel has a higher RVP because the fuel must be able to evaporate at a low temperature for the engine to run normally.
In 2021, Brazil's worst drought in almost a century threatened its electricity supply. [6] [7] Brazil relies on hydropower for two-thirds of its electricity.[8]Euractiv reported that European Commissioner for Climate Action Frans Timmermans told the European Parliament in Strasbourg that "about one fifth" of the energy price increase "can be attributed to rising CO 2 pricing on the EU's carbon ...
The international dependence of energy resources exposes countries to vulnerability in every aspect of life — countries rely on energy for food, infrastructure, security, transportation, and more. In the Scottish Independence debate, energy independence is a key argument in favour of Scottish exit.
Calculating fair value: By comparing implied volatility with historical volatility, you can determine whether an option is fairly priced. If IV is significantly higher than HV, it may suggest that ...
