Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

The many applications of flow measurement include uses in water supply, medical research, oil exploration, food processing and distribution of gas. The uses of this technology are very diverse, with ...

Among the first instruments plastics molders, extruders, and compounders are likely to consider when outfitting a new lab is a melt-flow indexer or “melt indexer.” Known as an extrusion plastometer in ...
