Public ISBD Titre : Float valve provides variable flow rates at low pressures Type de document : texte imprimé Auteurs : Merriam, J.L. Mention d'édition : Agricultural Engineering Department Polytechnic State University Editeur : Agricultural Engineering Department Polytechnic State University Année de publication : 1973 ISBN/ISSN/EAN : CI-08029 Note générale : "Semi-closed and closed pipeline sustems can provide water delivery that is flexible in rate duration with ""fringer-tip"" control at the ultimate point of application. Such delivery is essential for efficient and economical use of water an labor. The water source must be capable of supplying water at variable rates and duration therefire an on-farm reservoir is frequently necessary. The extra capital investment to construct such a system is economically justified by reduced annual costs of labor and increased irrigation efficiency. Semi-closed systems utilizing a float valve actuated by down-stream water levels, permits deliveries at low relatively uniform..."
