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, ...

As you wouldexpect, there are several areas within an engine where frictional losses are created, at the very minimum. Also consistent with conventional wisdom is the fact they are unavoidable and can ...
