There is no requirement to use the two components of DFS together; it is perfectly possible to use the logical namespace component without using DFS file replication, and it is perfectly possible to use file replication between servers without combining them into one namespace.
In 2016, the majority (51%) of the 8.4 million barrels per day (b/d) of crude oil produced in the Lower 48 states was light oil, or less dense oil with an API gravity of 40.1 or above. Light oil also made up more than half of the oil produced in 2015. API gravity is measured as the inverse of the density of a petroleum liquid relative to water. The higher the API gravity, the lower the density of the petroleum liquid, so light oils have high API gravities.
Conversion in API degrees is for liquids with specific gravity lower than 1, which means for liquids lighter than water. Conversion in Baume degrees is for liquids with specific gravity higher or lower than 1, which means for liquids heavier or lighter than water. Calculator use following equations for conversion between API and Baume degrees. For oils specific gravity SG(60OF/60OF): For liquids lighter than water SG(60OF/60OF): For liquids heavier than water SG(60OF/60OF): As the density of water at 15OC is 999 kg/m3, density of oil or other liquid can be calculated as: water density x SG(60OF/60OF).
