Many homeowners notice that plumbing noise becomes more prominent at night. Sounds such as knocking, ticking, banging, humming, or rushing water often seem louder when the building is quiet. While ...

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 ...

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.

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 ...

In pressure relief systems, accurately estimating temperature changes during fluid flow is vital for relief piping ...

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, ...
