Study of four options for determining hydrostatic pressure on a plane surface by the three-command method K123

Four different options of modern engineering calculation for solving one standard problem were studied. Four different modern options for solving one standard problem based on the new author's method of three K123 commands. The basis of the author's method is the geometric content and formulation of the problem of determining the hydrostatic pressure on a flat surface using the example of a standard typical problem of hydrostatics. The algebraic component of the implementation of the problem solution is used as an auxiliary calculation technology.A full factorial experiment was conducted. According to the results of the work, the set goal was achieved - the total number of factors was reduced. Based on the methods of statistical analysis, the following conclusions were obtained: a statistically significant relationship was established between the use of concrete pipes at a low speed and the largest number of pipeline accidents. The material of the pipeline and the speed in it turned out to be the most influencing factors on the life of the pipeline and the number of accidents on the pipeline. The purpose of the presented work is to show the relevance of the development of scientific foundations, new algorithms and corresponding calculation technologies in modern engineering hydraulic calculations, which include individual achievements - unfortunately missed in the domestic educational literature - of the fifth technological order: cybernetics, computers, numerical methods, communication.
