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 ...

A novel approach using computational fluid dynamics techniques provides a way for determining the characteristics of gas passing through a gas-lift valve. In the method, CFD calculations numerically ...

An online residential/light commercial suite of Geothermal System Design Calculators is available. The free calculators provide comprehensive design tools, concentrating on the ground loop and pump ...

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 ...
