Tests of a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a pipeline transporting a non-Newtonian fluid, such as most crude oils and ...

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, ...

Values of this expression for typical published FBBV C values range from 0.10 to 0.25, clearly exceeding the threshold value. A second challenge related to the ultrahigh capacities of these valves is ...

This article describes how a multivariable pressure transmitter with built-in dynamic compensation can correct for many of the errors and inaccuracies that can occur in differential pressure based ...

Too often, pneumatic circuits are sized based on the valve’s flow coefficient, C v, without considering other system components. In the past, focusing on the valve alone often sufficed because air was ...
