Temperature as a factor of energy consumption in pipeline network operation

The problem of evaluating the influence of the temperature factor on the electricity consumption for the transportation of water in pressure pipes made of suitable materials is an integrated approach that includes, as a prerequisite, conducting bench hydraulic experiments to determine the hydraulic friction coefficient, as well as calculation and analytical operations, followed by widely used software automated programs. The symbiosis of experimental and analytical approaches used in the research enable a faster solution of such an important matter as managing the operation of pressure pipelines and getting the optimal electricity consumption. The pipes made of non-plasticized polyvinyl chloride are subject to a detailed study. To provide the best objectivity when comparing the experimental and design values of the desired issues, the algorithms of automated programs have a number of restrictive bands on a number of indicators such as the Reynolds number, the ratio of dynamic viscosities, respectively, related to the temperatures of the pipe walls and transported water, as well as the water kinematic viscosity. Modeling based on the results of the automated calculations and their subsequent analysis enables determination of the electricity consumption amount under the appropriate temperature conditions of the pipeline operation along with identification of the optimal parameters for controlling the water transportation process, which allows the utility managers to provide an effective management of the water transportation process, helping to ensure minimal energy consumption. The herein submission of the article materials can be used to solve similar problems in order to determine the most economical option for designing and operation of pressure pipelines made of different materials in a wide range of water flow rates and pipe diameters.
