Calculation of Effective Parameters of Distribution Drainage Pipelines

Pressure distribution drainage pipelines are one of the main elements of reclamation systems, ensuring optimal moisture conditions for agricultural production. The aim of the work is to develop a reliable methodology for hydraulic calculation of the investigated pipes, taking into account the structural and filtration characteristics of the surrounding soil and the lateral surface of the pipes. The research utilized a combination of experimental measurements and analytical processing of the obtained data, complemented by the results of solving the initial theoretical dependencies describing the fluid motion with variable flow rate in pressure distribution drainage pipes. Relatively simple and convenient calculation formulas were obtained, allowing the determination of effective characteristics of distribution drainage pipes, namely, diameter and length. The proposed calculation methodology will be useful in real-life design of distribution drainage pipelines in reclamation systems, as it allows for rational calculation of their parameters, significantly reducing construction costs and ensuring optimal operating conditions of reclamation systems.
