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.

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 ...

A new portable, space-saving bench system has been designed for accurate measurement of friction pressure in slick water ...

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