A comparison of fixed and rotating spray plate sprinklers

A comparative study of two types of spray sprinklers was performed. Rotating spray plate sprinklers (RSPS) and fixed spray plate sprinklers (FSPS) were evaluated individually in open field conditions. The water distribution, wind drift and evaporation losses during the evaluations were measured under low, medium and high wind speed conditions with three nozzle diameters and two nozzle heights above the soil surface. 1 Soils and Irrigation Unit, Servicio de Investigación Agroalimentaria, DGA, P.
