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, ...

A phenomenological model is proposed in this paper for simulating the effect of wall friction in turbulent pipe flows.The flow in this model is divided into two regions: wall region and core region.

Fluid flow friction factors serve as a cornerstone in understanding and predicting the resistance encountered by fluids moving through conduits. These dimensionless parameters are essential in both ...

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 ...

The goal was to determine how these factors relate to the frictional resistance of the flow going through the pipe. "Our data showed that the famous and classical laws for flow friction are only ...

Turbulence is one of the great mysteries of modern science. It is also one of the most important, as most of the flows we’re interested in are turbulent. In some applications, such as industrial ...

This latest addition to the 6700 Friction Flow Loop product line delivers advanced testing capabilities in a portable, space-saving design.

The 6700-M Mini Loop is a compact bench system designed for precise measurement of friction pressure in slick water ...

"We found that sipping through a straw defies all the previously known laws for the resistance or friction of flow through a pipe or tube," explains Leif Ristroph, an associate professor at New York ...
