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 ...

Going with the flow: does an extra term lead to a better model of turbulence? (Courtesy: iStock/Mumemories) Identifying universal laws within fluid mechanics is notoriously difficult. So it has come ...

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, ...
