has long been used for calculating the friction factor, f, for incompressible and some compressible flows in uniform pipes, ducts, and conduits. It is asymptotic to both the accepted smooth-surface ...

Pipe jacking is a trenchless construction technique that employs hydraulic jacking forces to install pipelines beneath urban areas, minimising surface disruption. This method is increasingly vital ...

Rain for Rent’s mobile app features hydraulic calculation and engineering tools for on-the-fly pump calculations while in the field or office. The comprehensive suite of hydraulic estimation tools ...

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, ...

The idea is not a new one: Use composites to reline underground pipe without the time, effort, and expense of digging up all that dirt. Currently, there are two types of lining technology. One is a ...
