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 ...

This file type includes high resolution graphics and schematics when applicable. Proper size and installation extend the life of gas springs and dampers. Gas springs help lift loads or open doors or ...

A new equation for accurate approximation of the Moody friction factor in the general gas-flow equation better approximates a wide range of Reynolds numbers than previously published equations. Other, ...
