Uniformidade de aplicação de água do aspersor PLONA-RL250 em sistemas fixos de irrigação.

Abstract

Simulated values of water application uniformity of stationary sprinkler systems operating with a PLONA-RL250 under different spacings are presented. Simulated values were presented in four different groups. Each group contains working pressure and nozzle size combinations that determine the occurrence of radial profiles with the same geometric shape (I, II, III or IV). For a square disposition, sprinkler spacings near the sprinkler radius value result in higher uniformity values. For a rectangular disposition, sprinkler spacing along the lateral and between lateral lines of 50% and 80% of the sprinkler wetted radius, respectively, led to the higher.
