Specific gravity of a liquid is the ratio of the density of the liquid at 60°F to the density of pure water. API gravity is…
Choking, or expansion of gas from a high pressure to a lower pressure, is generally required for control of gas flow rates. Choking is achieved…
In dispersed gas units gas bubbles are dispersed in the total stream either by the use of an inductor device or by a vortex set…
A double-pipe exchanger is made up of one pipe containing the tube fluid concentric with another pipe, which serves as the shell. The tube is…
