Résumé:
The uniformity of water application in irrigation is an important aspect of system efficiency.
This work was carried out in order to check the hydraulic performance of the
emitterHadar 7110 model with 1.2 mm nozzle orange and nominal flow of 75 Lh-1
for pressure of 200 kPa, manufactured by Naandan. The emitter were subjected to a pressure
variation of 100, 150, 200, and 250 kPa through a regression analysis we obtained the
characteristic curve, coefficient of uniformity of Christians (CUC), coefficient of uniformity
of distribution (CUD) , standard deviation and coefficient of variation of manufacturing
capacity (FVC). Using 20 transmitters with a test time of 6 minutes in a line of 10 m where 5
microsprinklers were evaluated at a time. Can be seen the emitter had a flow rate of 73.47 lh"1
