GONZALEZ-QUIRINO, José Guadalupe et al. Deterministic equation for hydraulic system design multiple outlet irrigation. Rev. Mex. Cienc. Agríc [online]. 2021, vol.12, n.5, pp.777-789. Epub 14-Mar-2022. ISSN 2007-0934. https://doi.org/10.29312/remexca.v12i5.2986.
In the design of multi-outlet irrigation systems, it is necessary to calculate the frictional energy losses in pipes and determine the most economical and optimal diameter, for this, there are the equations of Manning, Hanzen & Williams and Darcy & Wesbach. According to the above, the objective of this work was to perform a mathematical physical analysis of the equations of energy losses due to friction in pipes and fittings to generate at least one deterministic equation based on the Manning and Darcy & Wesbach equation for the hydraulic design of multi-outlet irrigation and reduce high costs in the operation of agricultural irrigation equipment. The study was conducted in spring 2021, at the National Technological Institute of Mexico, Technological Institute of Torreón campus. The equations of localized and frictional energy losses (Darcy & Wesbach and Manning) were algebraically merged, and three deterministic equations were obtained for the design of multiple outlets with a relative error range from -0.009 to 0.209% in relation to the equation proposed by SARH 1979 (CENAMAR).
