Abstract:
The ability to predict the hydraulic performance of a pipe network during its working life
plays an important role in the planning and design of water supply schemes. The nominal
diameter and the friction factor of pipes are two essential parameters in the analysis of
pipe networks. The values of these parameters are usually known for commercially used
new pipes. With aging, corrosion and scaling in pipes may cause a reduction of diameter
and an increase in surface roughness, leading to a reduction of carrying capacity. In this
experimental study, attention is focused on the effect of scaling on frictional losses of
commercially used pve pipes.
