Abstract

This work was carried out at “Ceballos” Citrus Company with the objective of evaluating the phenomenon of hydraulic hysteresis in emitters and self-compensating irrigation tapes. The emitter models Vip Line with a nominal flow of 3.9 L/h and Naan PC with a nominal flow of 4 L/h were evaluated as well as the Aqua Traxx Irrigation Tape. The determination of the flow-pressure curve was performed by measuring the hysteresis phenomenon in the backward direction. These self-compensating emitters are affected by the phenomenon of hysteresis of the material, an aspect that is observed in the difference of the curves q = f (h) registered with ascending and descending pressures and whose equations are of the polynomial type obtained in experimental conditions with coefficients of relation higher than 90%.
