Sprinkler Rotation Nonuniformity and Water Distribution

  title={Sprinkler Rotation Nonuniformity and Water Distribution},
  author={Jiazhi Li and Hiroyuki Kawano},
The range of sprinkler rotation nonuniformity for commercial sprinkler products and how this nonuniformity affects overlapped water distribution patterns is of concern to manufacturers, system designers, and users. Sprinkler rotation tests for a wide range of sprinklers showed that the maximum relative rotation deviation, MRD, as defined in this article, usually varied within a range of 20% under practical riser installations. The value of MRD increased significantly with increasing sprinkler… CONTINUE READING
