Simplified form of the normative dependence for hydraulic calculation  of pipelines made of polymer materials (to be discussed)

Summary

Hydraulic calculation of pipelines (pipes) made of polymeric materials is regulated by the acting regulatory documents (SP 40-102-2000). In the aggregate a method (sequence) of hydraulic calculation of pipelines made of polymeric materials with the use of a simplified form of the normative dependence for determining hydraulic resistance coefficient  is proposed. The calculation method is of practical interest because it is confined to the determination of three values included into the normative calculation dependence for the subsequent determination of head losses along the pipeline length. The hydraulic calculation method includes new parameters: hydraulic potential of a pipeline, effective fluid flow rate, effective roughness of the inside pipe surface, effective pipe diameter. These parameters and the Calculation Method have been included into the 3rd edition of the complemented material of Reference book «Tables for hydraulic calculation of pressure polyethylene pipes» (2017). The simplified form of the normative dependence and the method of making hydraulic calculations of pipelines made of polymeric materials can be considered to be included into the revised version of SP 40102-2000.
