Abstract
The article presents theoretical results on determining optimal (best) parameters of a new wide-spread sprinkler using the Rechtshafner method. The coefficients B0, Bi, Bij and Bii were obtained based on experimental data and presented in form of a mathematical model, the significance of which was assessed using the Student's test. For identifying the correctness of the experimental results obtained using the Fisher criterion studied the coefficients gave an error of 5%, which is quite acceptable. As a result of the compromise solution task, we determined the optimal values of factors for the wide-cut section sprinkler.
Introduction. Design engineers are tasked with developing a new generation of irrigation equipment using modern construction materials, with reduced energy consumption, with maximum automation, and a wide range of adjustable parameters when used for certain irrigation conditions. The quality of irrigation with a sprinkler is characterized by the uniform distribution of irrigation water over the area. To determine the quality of uniform distribution of artificial rain by widespan sprinklers, the coefficient of effective irrigation is used, which characterizes the uniformity of the distribution of irrigation water in the irrigated area.
Object. Wide-span pivot irrigation machine.
Materials and methods. Theoretical studies were carried out to determine the optimal parameters of a new wide-spread sprinkler using the Rechtshafner method.
Results and conclusions. The coefficients В0, Вi, Вij and Вii were obtained based on experimental data and presented in the form of a mathematical model, the significance of which was assessed using the Student’s ttest. To determine the correctness of the obtained experimental results using the Fisher criterion, the studied coefficients gave an error of 5%, which is quite acceptable. As a result of solving the compromise problem, we determined the optimal values that ensure uniform distribution of rain with an effective irrigation coefficient of at least 0.8.
