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 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, ...

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 ...

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 ...

One of my highly intelligent residents recently inquired about my personal fluidic settings for our phaco machine platform. I told him the numbers: maximum vacuum of 250 mm Hg, flow rate of 45 cc/min ...

IN the 1908 Christian Herter Lectures at Bellevue Hospital, Starling 1 emphasized the important influence of changes in hepatic interstitial-fluid formation on flow and composition of thoracic-duct ...

Testing sterilizing grade filters using integrity testers has become a standard method in biopharmaceutical production and quality assurance. In accordance with international regulations and ...
