In the search of a Central Pivot's best operational performance, the equipment's electric and mechanical characteristics, plus the realistic knowledge of the hydraulic relationships to which the "system" as a whole is submitted, is a must for its proper sizing in function of its components adequate choice. The presence of different sprinklers, featuring diverse diameters and hydraulic characteristics, pressure regulators and the possibility of the presence of a larger sprinkler with a booster on the network, allied to the necessity of attending the physical-natural restrictions which wrap-up agriculture production technology, properly express the arduous task of developing irrigation and drainage projects seeking a harmonic arrangement between a uniform application and the efficient use of water catchment's reserves. Leaning towards the discussion of this subject and seeing the importance of the presence of automatic irrigation systems on a large scale agricultural productivity, the present paper presents its basic considerations under the mathematical modeling scope of the sprinkler's flow distribution along the Central Pivot's line, so as to harmonize both their continuous and discrete flows, aiming at a better aspersed water uniformity application.
