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 ...

Chezy and Manning developed equations that are used to determine the average volumetric flowrate in open channels. This article explains a laboratory method that was developed and tested to further ...

Unique behavior of gas condensate wells is characterized by rapid well production loss. Condensate rapidly builds up around the wellbore, reducing gas permeability and gas deliverability, when the ...

A flow rate test is used to work out the melt flow rate (MFR) of a thermoplastic material. According to ASTM 1238, “Method A” test involves the collection of extrudate from the die over a set period ...

The flow of all fluids, whether liquid or gas, will have one of three states: laminar, turbulent, and transitional. This article discusses flow principles and pressure-based flow measurement. Laminar ...

When thinking mathematically, most people think in proportions. For example, if someone is baking cookies and they want to make a double batch, they intuitively know they need to double the amount of ...

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 ...
