Idizayini yokufafaza ngomlilo incike kakhulu kugunya nasendaweni amakhodi. Kodwa-ke, imigomo yayo engaphansi yokwakheka iyafana nakwamanye amazwe. Lolu hlelo lokusebenza lokufafaza luqukethe amanye amathuluzi wokwenza okuvamile ngokulandelayo:
1) I-formula ye-QKP - ifomula ye-K-factor ku-K = Q / (P) ^ 0.5 isetshenziselwa ukubala isilinganiso sokugeleza kokuphuma endaweni eyi-nozzle noma ukuphuma.
2) Ithuluzi lokuguqulwa kwamayunithi we-K-Factor - kuvezwe amayunithi ahlukahlukene ahlukene, futhi kungadida.
3) I-Hazen-Williams yokubala ukulahleka kokuqhekeka kwengqondo - indlela evame ukwamukelwa yokuthola ingcindezi yokwehla ngenxa yokulahleka kwengxabano e-pipework.
I-4) Ukulinganisa okugelezayo emhlanganweni we-hydraulic - at hydraulic junction point, flow balancing kuyadingeka ngoba kungaba nengcindezi eyodwa ngasiphi isikhathi.
I-5) Isibali sokubala se-orifice yeplate - Ipuleti le-Orifice lifakwa ohlelweni lwamapayipi omlilo ukudala ukulahleka kwengcindezi ethile nokunciphisa ukugeleza ukufeza ibhalansi ye-hydraulic.
6) Ukuvinjwa kogongolo - itafula lokubuka okulungele izidingo zobukhulu, ikakhulukazi uma usendaweni.
7) Imingcele yepompo ye-NFPA 3-point pump - i-NFPA 20 ilawula ijika lomlilo wokusebenza kwepompo ukugwema ijika elijike kakhulu.
8) I-NFPA density / curve yendawo - thola abantu noma indawo yamaqembu enobungozi.
9) Ukubalwa kwabantu / kwendawo - kubalwa inani le-fafaza endaweni yomklamo, ukugeleza kwefafaza nokucindezela.
