AbstractThe utiliz tion of saline water for irrigation requires its dilution with sweet water. This is carried out in so-callEd“distrilution”networks, which differ from conventional water distribution systems in that they contain mixing junctions. Mixing can take place in an open tank at atmospheric pressur , or in a pressurized line. Both methods are discussed, and various possible designs for the mixing junction and its control system d scribed. A compu er program, intended as d sign aid, for simulating steady-st te flows in the juncion is discussed. Finally, an existing mixing junction is described, and its control simulted on a hybrid computer.
