1. Te whakataurite i te tukanga whakaputa
Te tukanga whakaputa opaipa maitai tuitui tikahe tino māmā noa iho. Ko ngā tukanga whakaputa matua he hononga tika-whakapiripiri auau-teiteipaipa maitaimepaipa maitai tuitui tika i whakarewaina ki te pewa i raro i te waiHe pai te whakaputa o ngā paipa maitai tuitui tika, he iti te utu, ā, he tere te whanaketanga.
Te kaha opaipa maitai porowhitahe teitei ake i te paipa maitai tuitui tika. Ko te tukanga whakaputa matua ko te whakarewa pewa i raro i te wai. Ka taea e ngā ngongo maitai porowhita te whakaputa i ngā ngongo whakarewa me ngā diameter rerekē o ngā pireti o te whānui rite, rāneingā ngongo whakarewame ngā diameter nui ake mai i ngā pereki whaiti.
Heoi, ki te whakaritea ki ngā paipa maitai tuitui tika o te roa ōrite, kua piki ake te roa whakarewa mā te 30% me te 100% ia, ā, he iti te tere whakaputa. Nō reira, ko ngā paipa maitai whānui te nuinga o te wā ka whakarewahia mā te whakarewa porowhita, ā, ko ngā paipa maitai whānui iti te nuinga ka whakarewahia mā te whakarewa tuitui tika.
I te whakaputangā paipa maitai tuitui tika nui te whānuiI roto i te ahumahi, ka whakamahia te hangarau whakarewa āhua-T, arā, he iti noa ngā paipa maitai tuitui tika ka honoa ki te pūtake, ka honoa kia tutuki ai te roa e hiahiatia ana o te kaupapa. Ka tino piki ake ngā hapa o ngā paipa maitai tuitui tika āhua-T, ā, ka nui te ahotea toenga whakarewa o te whakarewa āhua-T. I te nuinga o te wā ka pāngia te konganuku whakarewa e te ahotea toru-axial, ka nui ake te tūponotanga o te pakaru.
Hei tāpiritanga, e ai ki ngā ture hangarau mō te whakarewa pewa i raro i te wai, me wero pewa ia whakarewa me te tinei pewa. Heoi, kāore e taea e ia paipa maitai te whakatutuki i tēnei whakaritenga i te wā e whakarewa ana i te hononga porowhita, nō reira ka nui ake ngā hapa whakarewa ka puta i te wā e tinei pewa.
2. Te whakataurite i ngā tawhā mahi
Ina pāngia te paipa e te pēhanga ā-roto, e rua ngā ahotea matua ka puta i runga i te pakitara o te paipa, arā, ko te ahotea radial me te ahotea axial. Ko te ahotea whānui i te hononga whakarewa, ko α te koki porowhita hononga whakarewa opaipa maitai porowhita.
Ko te ahotea whānui i te hononga porowhita te ahotea matua o te paipa maitai tuitui tika. I raro i te pēhanga mahi ōrite, he iti ake te matotoru o te pakitara o ngā paipa maitai porowhita me te diameter paipa ōrite i te matotoru o ngā paipa maitai tuitui tika.
