Ko ngā tawhā āhuahanga o te mīhini whakaranu rīpene te paearu whakauru matua mō te whiriwhiri taputapu me te tahora tukanga. I roto i te mahi hangarau, ko te kupu "āhuahanga" e kapi ana i ngā āhuatanga e toru e hono ana engari he rerekē: te kaha rōrahi (e whakatau ana i te kaha tukatuka puranga), ngā āhuahanga āhuahanga o waho (e whakatau ana i te tapuwae tāutanga me te wāhi upoko e hiahiatia ana), me ngā āhuahanga o ngā wāhanga neke o roto (e whakatau ana i te whānuitanga whakaranu me te ōritetanga). I te katoa, ka hangaia e ēnei āhuatanga e toru he kōtaha āhuahanga whānui o te mīhini whakaranu rīpene.
Ⅰ. Ngā Whakatakotoranga Rōrahi: Ngā Ahu Ingoa me te Pūmanawa Tuturu
Ko ngā tohu tauira mō ngā mīhini whakaranu rīpene e ahu mai ana i te rōrahi katoa, e pā ana ki te rōrahi āhuahanga o te wāhi o roto i roto i te awa āhua-U o te rūma whakaranu, e inehia ana i roto i ngā rita (L) mita pūtoru rānei (m³). Ko ngā whakatakotoranga noa mai i ngā tauira taiwhanga 50-rita ki ngā waeine tauine ahumahi 30,000-rita.
He mea nui kia tino wehewehea tēnei mai i te rōrahi mahi, e pā ana ki te rōrahi e nohoia ana e te rauemi i te wā e mahi ana. Nā te hiahia mō te wāhi wātea i te tihi e whakatakotoria ana e te kaupapa whakaranu o ngā mīhini whakaranu rīpene, e taunakihia ana kia 40% ki te 70% o te rōrahi katoa te tere whakakī e taunakitia ana, me te uara hoahoa noa o te 60%. Ko te tikanga o tēnei he mīhini he 3,000 rita te rōrahi katoa, ā, he kaha tukatuka puranga tūturu tōna e tata ana ki te 1,800 rita o te rauemi.
I ahu mai tēnei here i ngā āhuatanga ā-rahi o te hanganga rīpene tīwiri: i te hurihuri o ngā rīpene o roto, o waho hoki, me pana e rātou te rauemi mai i ngā pito e rua ki waenganui, mai i waenganui rānei ki ngā pito e rua, me te hanga i te takahurihuri porohita i te wā kotahi. Mēnā he teitei rawa te tere whakakī, ka nui ake te rauemi i te awhe whai hua o ngā rīpene, ā, kāore e taea te whai wāhi ki te nekehanga whakawhiti, ka pā tika ki te ōritetanga o te ranunga.
Tuarua.Ngā Ahu o Waho: Te Roa, te Whānui, te Teitei, me ngā Here Wāhi
He hoahoa whakapae te mīhini whakaranu rīpene, ā, ko ōna inenga o waho ka whakatauhia e ngā tawhā āhuahanga e whai ake nei:
Roa (L): Ka whakatauhia e te roa o te oko whakaranu me ngā rahinga tāutanga tuaka o ngā pereti pito, ngā whare whāriki, me te whakaiti taputapu.
Whānui (W): I whakatauhia e te whānui o waho o te awa āhua-U me ngā toronga taha o te motuka me te whakaiti taputapu
Teitei (H): Ka whakatauhia e te tawhiti mai i te raro o te awaawa ki te taupoki o runga, me te teitei hanganga o te takirere tukunga o raro me te tomokanga whāngai o runga
III.Ngā Ahu o ngā Wāhanga Nekehanga o Roto: Te Diameter me te Piko o te Mata Tīwiri
Ko ngā tawhā ā-rahi o ngā mata tīwiri tonu e whakatau tika ana i te whānuitanga o te mahi whakaranu:
Te Diameter o Waho o te Mata Tīwiri: E whakatau ana i te whānuitanga o te takahuri porohita o te rauemi. Ko te nui ake o te diameter o waho, ko te matotoru ake o te paparanga o te rauemi e nekehia ana e te hurihanga kotahi. I te nuinga o te wā, he iti ake te diameter o waho o te mata tīwiri i te whānui o roto o te takotoranga āhua-U, me te pupuri i te āputa i waenga i te mata me te tinana takotoranga i waenga i te 3 me te 10 mm hei ārai i te piri o te rauemi.
Teitei: Ko te teitei o ngā rerenga tīwiri o roto, o waho hoki e whakatau ana i te tawhiti tuaka e panaia ana te rauemi i ia hurihanga. I roto i ngā hoahoa noa, ko te ōwehenga o te teitei ki te whānui o te rerenga tīwiri he 0.8–1.2. Ka kaha ake ngā kaha kutikuti o te teitei iti, e pai ai mō ngā rauemi e ngawari ana ki te whakaemi; ka nui ake te teitei ka tere ake te kawe tuaka, e pai ai mō ngā rauemi he pai te rere.
Ko ngā rerenga tīwiri o roto, o waho hoki, he tikanga whakamahi i tētahi whirihoranga paparua, hurihuri-whakamuri: ka panaia e ngā rerenga o waho te rauemi ki tētahi pito, ko ngā rerenga o roto ia ka pana ki te taha kē, ka tutuki ai te ranunga āwhiowhio puta noa i te pahu katoa. Ko te rerekētanga ā-ahu i waenga i ngā huinga rerenga e rua (ko te whānui rerenga o roto he 0.4 ki te 0.6 ngā wā i te whānui rerenga o waho) te mea e whakarato ana i te kaha akiaki mō te nekehanga rauemi radial.
