Abstract (en)
The flow in sewerage pipes is free-surface and the pipe throughput depends on pipe surface roughness and air layer resistance. This article analyses the impact of pipe joints and air resistance upon the change of hydraulic friction coefficient values, depending on variations in Re number values. Hydraulic losses at plastic pipes might be calculated as losses at hydraulically smooth pipes, multiplied by correction coefficients that assess losses at pipe joints and air resistance. The values of coefficients and the methods of calculation thereof are provided. The calculation results are compared with the experimental data of other authors.
