Abstract
When designing and reconstructing engineering networks of urban infrastructure, design organizations use a set of classical formulas for hydraulic calculation of pipelines. They don’t take into account changes in hydraulic potential during operation, and it leads to significant errors. This justifies the need to develop and refine reference manuals for hydraulic calculation of worn-out metal water supply, sewerage and heating networks of urban infrastructure. A specific example graphically demonstrates the influence of the thickness of the layer of internal deposits on the accuracy of the hydraulic calculation of pipes, i.e. on the determination of the parameters of their hydraulic potential. Based on the proposed methods of hydraulic calculation of pipes, we proved the relevance of revise the special reference manuals with taking into account actual changes in the values of hydraulic characteristics of metal pipelines in the process of their operation, in particular, the value of the coefficient of hydraulic efficiency of the pipeline.
