The geometrical parameters nke nozzle nwere mmetụta dị ukwuu na cavitation eruba na cavitation wear.Shervani et al. na Lee et al. kwubiri site na nyocha ịme anwansị na mmụba nke taper nke nozzle nwere ike belata mmetụta nke ọdịda afụ na cavitation iyi n'ime elu nke nozzle, yana na ntụkwasị obi nke nozzle ga-akawanye mma.
