Urugero rwa Gray rwerekeza ku nzira y'amazi ishobora gutera ingano zitandukanye (diameter, umubare) amatonyanga y'irangi ry'irangi hakurikijwe ivya nkenerwa imwe .
Urugero rw’imvi rwa nozzle rugaburwamwo 4-8, iki gice kigereranya igice c’amatonyanga manini y’irangi, 4 ni uko: amatonyanga manini agizwe n’amatonyanga ane mato, 8 ni uko: amatonyanga manini agizwe n’amatonyanga umunani y’amatonyanga .
Uko bikora: Mu gice kimwe c’umutwe w’icapa, mu kugenzura ukuntu umubiri w’umuyagankuba unyiganyiga, kugira ngo utere amatonyanga imwe canke nyinshi z’irangi mu gihe gito cane, amatonyanga mato ashobora gushirwa mu matonyanga manini manini y’irangi.
Nk’akarorero: urusenga rwa 14PL, rwo gucapura n’ingero 8 z’imvi, Ivyo ni vyo bihimba vy’amatonyanga umunani 14PL, ubunini bw’amatonyanga y’irangi kangana n’amatonyanga 112PL y’irangi, 4 na yo ingana n’amatonyanga 4 *14=56PL.
Igihe ucapa igicuruzwa gifise ibara ry’umwiza n’umuco, igikorwa c’imvi ni ikintu gihambaye cane, ibi bikurikira ku bijanye n’igikorwa [nta gikorwa c’urugero rw’imvi], [n’igikorwa c’urugero rw’imvi], [urugero rw’impumuro + rukagabanuka] Mu gukoresha ihinduka igihe gucapura.
Nta gikorwa c’urugero rw’imvi, amatonyanga y’irangi apfukwa n’urushinge rw’irangi akozwe n’amatonyanga mato, nk’akarorero 14PL nozzle, ni ubunini bw’amatonyanga y’irangi ashobora kuba 14PL{2}} Birashoboka gusa kugabanya uburemere bw’ibara ry’agahama (DPI) igihe co gucapura ibice vy’umuco{3}}
Ukoresheje igikorwa c’ibara ry’umuhondo, ushobora gusohora amatonyanga mato kugira ngo yerekane amabara y’umuco, kandi uburemere bw’ico kigereranyo (dpi) ntibuhinduka .
