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 ...

Version 4 of the Bell & Gossett System Syzer® program for PC computers is available. It is an update of a tool for calculating flow rates and pressure drops in HVAC piping systems. The program ...

A method has been developed that allows direct, accurate calculation of recovery efficiency for Claus sulfur-recovery units (SRU). The calculation combines feed-gas data and tail-gas composition to ...

Start with flow rates, not port sizes, to properly spec control valves. Selecting solenoid and control valves seems like a straightforward process. Armed with orifice size or pressure differential, ...

This is the second of eight articles from our Nozzle Knowledge Series. Prefer to watch a video, click here. Flow rate, the volume of water passing through a nozzle, per unit of time, is clearly an ...
