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.

has long been used for calculating the friction factor, f, for incompressible and some compressible flows in uniform pipes ... and R e (Reynolds number) values without causing endless computations.

Reynolds developed a set of equations to describe the relationship between the speed at which a fluid flows and the friction that is created between it and the pipe. Engineers still use Reynolds's ...

An experimental facility has been constructed to investigate a fully developed turbulent pipe flow ... agreement (on friction factor and turbulence intensities for example) between investigations or ...
