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 ...

When water flows through a pipe, pressure is lost due to friction with the pipe walls, as well as at bends, valves, and ...

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 ...

In today's episode, Shini tells us about Static and Kinetic friction. Why is it hard to move a heavy bookcase across a carpeted floor? And why is it easier to keep it moving than it was to get it ...

In this chapter we gathered the three main problems one faces in metal-forming simulation once the element and the constitutive formulation are chosen: The contact problem is still among the most ...
