Análisis estadístico de los factores que intervienen en el desgaste de la tubería de regadío de la comunidad San José la Silveria, parroquia San Andrés, provincia de Chimborazo

Abstract

The objective of this investigation was to analyze the factors to consider in the irrigation pipe wear at San José la Silveria Community, San Andrés parish, Chimborazo province. An Exploratory Data Analysis (EDA), the Kolmogorov-Smirnov test, the Bootstrap method and the Student's T-test were carried out, based on the secondary data that had their respective thickness measurement in the year 2019. As a second pillar of investigation, the RStudio software was used to perform the statistical analysis of the data based on the descriptive measures that expose four variables as reference points (A, B, C, D), which are geometric locations of the irrigation pipe, followed of the comparison between the reference (A-C, B-C, D-C), to contrast the least wear in the 15 sections of the pipe. In addition, in the Points Before Welding (PAS) and Points After Welding (PDS). With the RStudio software, it was shown that the thicknesses at reference points A, B and D present a minimum wear of 25,4%, and reference point C presents the greatest wear, with a progressive loss of 74,6%. , causing cuts, scratches, chipping and thus reducing the useful life of the pipe. It is concluded that the trend that has less thickness is found in reference C, since the most predominant type of wear is shown through its interpretations, which, in this investigation, was wear by abrasion. Finally, it is recommended that San José de la Silveria Community and its surroundings carry out preventive maintenance mingas, applying anticorrosive paint on the external surfaces of the irrigation pipe, to promote the extension of the useful life of the irrigation system and contribute to the production of the area.
