HERNANDEZ-RODRIGUEZ, Alexander et al. Mathematical models for estimating parameters of a pumping system in furrows irrigation. Rev Cie Téc Agr [online]. 2024, vol.33, n.1  Epub 01-Mar-2024. ISSN 2071-0054.

The study was carried out at the Tío Pedro farm in the municipality of Venezuela, in the province of Ciego de Ávila, with the objective of proposing mathematical models to estimate the hydraulic parameters of a pumping system using the furrow irrigation technique for the cultivation of black bean. The results showed expected fluctuations in hydraulic parameters such as flow rate, head, hydraulic power, pumping time, and pumped volume. Functional relationships were found between flow and pumping head, as well as between hydraulic power, flow and pumping head. These ratios can improve pump system performance, save energy, and increase pump efficiency. In addition, functions were developed to predict the characteristic curves of the load, the efficiency of the pump and the system in general. These results can improve energy efficiency and water management in agriculture.

Palabras clave : Pumping Head; Flow; Electrical Power; Hydraulic Power.
