Introduction]“When you rub your hands together vigorously, they start to feel warm due to friction”—this is a phenomenon we ...

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. A new ...

A team of microsystems engineers at Université de Lyon, École Centrale de Lyon has developed a method to create a desired amount of friction between two flat surfaces without resorting to math. Their ...

Tests for a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a non-Newtonian fluid. Click on the pdf link below to view entire article ...
