Research on Multifunctional Nozzle

According to theory of the fluid mechanics,for example,the continuous equation of flowing stable fluid and so on,the multifunctional nozzle to be used for different hydraulic source of water was developed.We established a relationship between the quantity of moving nozzle rod and the throttling area of the nozzle.The optimum spout diameter and length of the nozzle from the test of the nozzle are selected by the orthogonal test.Therefore,the nozzle was tested and compared with the nozzle of the same kind.The spurt distance is (4.1m) farther than the nozzle of the same kind(4.2m).A method for designing the nozzle is provided.
