Analiza procesu hydraulicznego starzenia się żeliwnych i stalowych przewodów sieci wodociągowej we Wrocławiu
The values of the parameters describing the real wall roughness of cast-iren and steel pipes in service were determined by in-situ measurements and computer-aided modelling of the water-pipe network of Wrocław. The data sets obtained were subject to statistical analysis to quantify the effect of service time,pipe diameter and maximum flow velocity during 24 hours on the specific wall roughness values.
