Ka taea e ngā mīhini whakawhanui te whakamahi i te whakaiti pēhanga hei taraiwa i ngā mīhini hurihuri. Kei konei ngā kōrero mō te aromatawai i ngā painga pea o te tāuta i tētahi mīhini whakawhanui.
I roto i te umanga tukanga matū (CPI), "he nui te kaha e maumauria ana i roto i ngā takirere whakahaere pēhanga, me whakaiti te pēhanga o ngā wai pēhanga teitei" [1]. I runga i ngā āhuatanga hangarau me ngā āhuatanga ōhanga, he mea pai pea te huri i tēnei kaha hei pūngao miihini hurihuri, ka taea te whakamahi hei taraiwa i ngā whakaputa hiko, i ētahi atu mīhini hurihuri rānei. Mō ngā wai kore e taea te pēhi (wai), ka tutuki tēnei mā te whakamahi i te tāpine whakaora pūngao waipēhi (HPRT; tirohia te tohutoro 1). Mō ngā wai (hau) ka taea te pēhi, he mīhini pai te whakawhanui.
He hangarau pakari ngā whakawhanui me te maha o ngā tono angitu pērā i te pakaru wai (FCC), te whakamatao, ngā takirere tāone hau māori, te wehenga hau, ngā tukunga hau rānei. I roto i te kaupapa matua, ka taea te whakamahi i tētahi awa hau he iti te pēhanga hei akiaki i tētahi whakawhanui, engari "he rite tonu te putanga pūngao ki te ōwehenga pēhanga, te pāmahana me te tere rere o te awa hau" [2], tae atu ki te whaihua hangarau me te ōhanga. Te Whakatinanatanga o te Whakawhanui: Ko te tukanga e whakawhirinaki ana ki ēnei me ētahi atu āhuatanga, pērā i ngā utu pūngao ā-rohe me te wātea o ngā taputapu e tika ana a te kaihanga.
Ahakoa ko te turboexpander (he rite te mahi ki te tāpine) te momo whakawhanui tino rongonui (Pikitia 1), tera atu anō ngā momo e tika ana mō ngā āhuatanga tukanga rerekē. E whakaatu ana tēnei tuhinga i ngā momo matua o ngā whakawhanui me ō rātou wāhanga, ā, e whakarāpopoto ana me pēhea te aromatawai a ngā kaiwhakahaere mahi, ngā kaitohutohu, ngā kaitātari pūngao rānei i roto i ngā wehenga CPI i ngā painga ōhanga me te taiao pea o te tāutanga i tētahi whakawhanui.
He maha ngā momo whitiki ātete e rerekē ana te āhua me te mahi. Kei te Pikitia 2 ngā momo matua, ā, kua whakamāramahia pototia ia momo i raro nei. Mō ētahi atu kōrero, me ngā kauwhata e whakataurite ana i te tūnga mahi o ia momo i runga i ngā diameters me ngā tere motuhake, tirohia te Āwhina. 3.
Whakawhanui-turbo piston. Ko te mahi a ngā whakawhanui-turbo piston me te piston hurihuri he rite ki te miihini tahunga ā-roto e hurihuri whakamuri ana, e mimiti ana i te hau pēhanga teitei me te huri i tōna pūngao kua rongoatia hei pūngao hurihuri mā te poro crankshaft.
Tōia te kaiwhakawhānui turbo. Ko te kaiwhakawhānui turbine parai he rūma rere porowhita me ngā tara peere e piri ana ki te taha o te huānga hurihuri. He rite tonu te hoahoa ki ngā wira wai, engari ka piki ake te wāhanga whakawhiti o ngā rūma porowhita mai i te tomokanga ki te putanga, ka taea ai te whakawhānui i te hau.
Whakawhanui-ā-ira. He tomokanga tuaka me he putanga tuaka ngā whakawhanui-ā-ira, e āhei ai te hau ki te whakawhanui ā-ira mā roto i te impeller tāpine. Waihoki, ka whakawhanuihia e ngā tāpine rere tuaka te hau mā roto i te wira tāpine, engari ka noho rite tonu te ahunga o te rere ki te tuaka hurihuri.
E arotahi ana tēnei tuhinga ki ngā turboexpanders radial me axial, e matapaki ana i ō rātou momo momo, ngā wāhanga, me ngā āhuatanga ōhanga.
Ka tangohia e te turboexpander te pūngao mai i te awa hau pēhanga teitei, ka hurihia hei kawenga taraiwa. Ko te tikanga he compressor, he generator rānei e hono ana ki te pou. Ka kōpeke te turboexpander me te compressor i te wai i roto i ētahi atu wāhanga o te awa tukanga e hiahia ana ki te wai kōpeke, ā, ka whakanui ake i te whai huatanga whānui o te tipu mā te whakamahi i te pūngao e maumauria ana. Ka hurihia e te turboexpander me te kawenga generator te pūngao hei hiko, ka taea te whakamahi i roto i ētahi atu tukanga tipu, ka taea rānei te whakahoki ki te whatunga ā-rohe hei hoko.
Ka taea te whakauru i ngā miihini whakaputa-whakawhānui-turbo ki tētahi pou taraiwa tika mai i te wira tāpine ki te miihini whakaputa-turbo, mā roto rānei i tētahi pouaka miihini e whakaiti ana i te tere whakauru mai i te wira tāpine ki te miihini whakaputa-turbo mā te ōwehenga taputapu. He pai ngā painga o ngā miihini whakaputa-turbo taraiwa tika mō te whai huatanga, te tapuwae me ngā utu tiaki. He taumaha ake ngā miihini whakaputa-turbo pouaka miihini, ā, me nui ake te tapuwae, me ngā taputapu āwhina whakahinuhinu, me te tiaki auau.
Ka taea te hanga i ngā turboexpanders rere-roto i te āhua o ngā tāpine radial, axial rānei. Kei roto i ngā whakawhanui rere radial he tomokanga axial me te putanga radial kia puta ai te rere hau i te tāpine radial mai i te tuaka hurihuri. Mā ngā tāpine axial ka taea te rere hau axial i te tuaka hurihuri. Ka tangohia e ngā tāpine rere axial te pūngao mai i te rere hau mā roto i ngā vanes aratohu tomokanga ki te wira whakawhanui, me te piki haere o te horahanga whakawhiti o te rūma whakawhanui kia mau tonu ai te tere pumau.
E toru ngā wāhanga matua o te pūkaha whakaputa-turbo: he wira tāpine, he whāriki motuhake, me te pūkaha whakaputa-turbo.
Wira tāpine. He maha ngā wā ka hangaia ngā wira tāpine kia pai ake ai te pai o te aerodynamic. Ko ngā taurangi tono e pā ana ki te hoahoa o te wira tāpine ko te pēhanga tomo/putanga, te pāmahana tomo/putanga, te rere rōrahi, me ngā āhuatanga wai. Ina teitei rawa te ōwehenga kōpeketanga kāore e taea te whakaiti i te kotahi wāhanga, me whakamahi he turboexpander me ngā wira tāpine maha. Ka taea te hoahoa i ngā wira tāpine radial me te axial hei wira maha-wāhanga, engari he poto ake te roa axial o ngā wira tāpine axial, nō reira he iti ake. Me hiahia te hau ki ngā tāpine rere radial maha-wāhanga kia rere mai i te axial ki te radial, ka hoki ki te axial, ka nui ake te ngaronga waku i ngā tāpine rere axial.
ngā peera. He mea nui te hoahoa peera mō te mahi whai hua o te turboexpander. He rerekē ngā momo peera e pā ana ki ngā hoahoa turboexpander, ā, ka uru atu pea ki ngā peera hinu, ngā peera kiriata wai, ngā peera pōro tuku iho, me ngā peera aukume. He painga me ngā ngoikoretanga o ia tikanga, e whakaaturia ana i te Ripanga 1.
He maha ngā kaihanga turboexpander e whiriwhiri ana i ngā peera aukume hei "peera whiriwhiri" nā ō rātou painga ahurei. Mā ngā peera aukume ka kore e waku te mahi a ngā wāhanga hihiri o te turboexpander, ka whakaitihia te utu whakahaere me te tiaki i te roanga o te wā o te mīhini. Kua hangaia hoki kia tu atu ki te whānuitanga o ngā kawenga axial me radial me ngā āhuatanga taumahatanga nui. Ko ō rātou utu tīmatanga teitei ka whakakorengia e ngā utu huringa ora iti ake.
dynamo. Ka tangohia e te pūngao hurihuri o te tāpine ka hurihia hei pūngao hiko whai hua mā te whakamahi i tētahi pūngao hikohiko (he pūngao whakapūmau, he pūngao aukume tuturu rānei). He iti ake te tere whakatauranga o ngā pūngao whakapūmau, nō reira me whai pouaka miihini ngā tono tāpine tere teitei, engari ka taea te hoahoa kia rite ki te auau whatunga, ka kore e hiahiatia he puku auau rerekē (VFD) hei tuku i te hiko kua whakaputaina. Ko ngā pūngao aukume tuturu, i tētahi atu taha, ka taea te hono tika i te pou ki te tāpine me te tuku mana ki te whatunga mā te puku auau rerekē. Kua hoahoatia te pūngao ki te tuku mana mōrahi i runga i te mana pou e wātea ana i roto i te pūnaha.
Ngā Hiri. He wāhanga nui anō hoki te hiri i te wā e hoahoa ana i tētahi pūnaha turboexpander. Hei pupuri i te pai o te mahi me te tutuki i ngā paerewa taiao, me hiri ngā pūnaha hei ārai i ngā turuturu hau tukatuka pea. Ka taea te whakauru i ngā turboexpander ki ngā hiri hihiri, hiri tūmau rānei. Ko ngā hiri hihiri, pērā i ngā hiri labyrinth me ngā hiri hau maroke, ka whakarato i tētahi hiri huri noa i tētahi pou hurihuri, i waenganui i te wira tāpine, ngā peera me te toenga o te mīhini kei reira te mīhini whakaputa hiko. Ka tawhito ngā hiri hihiri i roto i te wā, ā, me tiaki me te tirotiro auau kia tika ai te mahi. Ina kei roto i te whare kotahi ngā wāhanga turboexpander katoa, ka taea te whakamahi i ngā hiri tūmau hei tiaki i ngā taura e puta ana i te whare, tae atu ki te mīhini whakaputa hiko, ngā puku peera aukume, ngā pūoko rānei. Ka whakaratohia e ēnei hiri ārai-hau he parenga pumau mai i te turuturu hau, ā, kāore e hiahiatia he tiaki, he whakatika rānei.
Mai i te tirohanga tukanga, ko te whakaritenga matua mō te tāuta i tētahi whakawhanui ko te tuku hau pēhanga-teitei (kāore e taea te whakapūtā) ki tētahi pūnaha pēhanga-iti me te rere e tika ana, te hekenga pēhanga me te whakamahinga hei pupuri i te mahi noa o ngā taputapu. Ka puritia ngā tawhā whakahaere ki tētahi taumata haumaru me te whai hua.
Mō te mahi whakaiti pēhanga, ka taea te whakamahi i te whakawhanui hei whakakapi i te takirere Joule-Thomson (JT), e mōhiotia ana ko te takirere whakatere. Nā te mea ka neke te takirere JT i te ara isentropic, ā, ka neke te whakawhanui i te ara tata isentropic, ka whakaitihia e te mea whakamutunga te enthalpy o te hau, ka huri i te rerekētanga enthalpy ki te mana o te pou, ā, ka iti ake te pāmahana putanga i te takirere JT. He mea whai hua tēnei i roto i ngā tukanga cryogenic, ko te whāinga he whakaiti i te pāmahana o te hau.
Mena he iti iho te rohe o te pāmahana hau putanga (hei tauira, i roto i te teihana whakakore pēhanga me pupuri te pāmahana hau ki runga ake i te hukapapa, te wai, te pāmahana hoahoa rauemi iti rawa rānei), me tāpiri kia kotahi te iti rawa te whakamahana. Whakahaerehia te pāmahana hau. Ina kei runga ake i te kaiwhakawhānui te whakamahana mua, ka whakahokia mai hoki ētahi o te pūngao mai i te hau whāngai ki roto i te kaiwhakawhānui, ā, ka piki ake te putanga mana. I ētahi whirihoranga e hiahiatia ana te whakahaere pāmahana putanga, ka taea te tāuta i tētahi whakamahana tuarua i muri i te kaiwhakawhānui hei whakarato i te whakahaere tere ake.
I roto i te Pikitia 3, e whakaatu ana te Pikitia 3 i tētahi hoahoa māmā o te hoahoa rere whānui o tētahi mīhini whakaputa whakawhanui me te whakamahana-mua e whakamahia ana hei whakakapi i te takirere JT.
I roto i ētahi atu whirihoranga tukanga, ka taea te whakawhiti tika i te pūngao i whakahokia mai i roto i te whakawhanui ki te pūwhakapūngao. Ko ēnei mīhini, e kiia ana ko "ngā kaiwhakahaere", he maha ngā wāhanga whakawhanui me te pēhanga e honoa ana e tētahi, neke atu rānei ngā pou, ā, ka uru pea he pouaka miihini hei whakahaere i te rerekētanga tere i waenga i ngā wāhanga e rua. Ka uru pea hoki he motuka tāpiri hei whakarato i te mana nui ake ki te wāhanga pēhanga.
Kei raro nei ētahi o ngā wāhanga tino nui hei whakarite i te mahi tika me te pumau o te pūnaha.
He takirere karo, he takirere whakaiti pēhanga rānei. Mā te takirere karo ka taea tonu te mahi ina kore te turboexpander e mahi (hei tauira, mō te tiaki, mō tētahi āhuatanga ohorere rānei), ko te takirere whakaiti pēhanga ia ka whakamahia mō te mahi tonu hei tuku hau nui ina nui ake te rere katoa i te kaha hoahoa o te expander.
Takirere kati ohorere (ESD). Ka whakamahia ngā takirere ESD hei aukati i te rere o te hau ki roto i te whakawhanui i roto i te āhuatanga ohorere hei karo i ngā kino ā-mīhini.
Ngā taputapu me ngā mana whakahaere. Ko ngā taurangi nui hei aroturuki ko te pēhanga tomo me te pēhanga putanga, te tere rere, te tere hurihuri, me te putanga mana.
Te taraiwa i te tere rawa. Ka tapahia e te taputapu te rere ki te tāpine, ka puhoi te hurihanga o te tāpine, ā, ka tiakina ngā taputapu mai i ngā tere rawa nā ngā āhuatanga tukanga ohorere ka kino pea ngā taputapu.
Takirere Haumaru Pēhanga (PSV). He maha ngā wā ka tāutahia ngā PSV i muri i te turboexpander hei tiaki i ngā paipa me ngā taputapu pēhanga iti. Me hoahoa te PSV kia tū atu ki ngā āhuatanga tino kino, tae atu ki te korenga o te takirere taha ki te whakatuwhera. Mena ka tāpirihia he expander ki tētahi teihana whakaiti pēhanga o nāianei, me whakatau e te rōpū hoahoa tukanga mēnā he pai te tiaki a te PSV o nāianei.
Whakamahana. Ka whakatikatikahia e ngā whakamahana te hekenga o te pāmahana i puta mai i te hau e haere ana i roto i te tāpine, nō reira me whakamahana te hau. Ko tana mahi matua he whakanui ake i te pāmahana o te rere o te hau e piki haere ana kia mau tonu te pāmahana o te hau, ka waiho te whakawhanui ki runga ake i te uara iti rawa. Ko tētahi atu painga o te whakanui ake i te pāmahana ko te whakanui ake i te putanga hiko me te ārai i te waikura, te hauhautanga, ngā waiariki rānei ka pā kino ki ngā pūwero taputapu. I roto i ngā pūnaha kei roto ngā whakawhiti wera (e whakaatuhia ana i te Pikitia 3), ko te pāmahana hau ka whakahaeretia mā te whakahaere i te rere o te wai wera ki roto i te whakamahana. I roto i ētahi hoahoa, ka taea te whakamahi i te whakamahana mura, i te whakamahana hiko rānei hei utu mō te whakawhiti wera. Tērā pea kei roto kē ngā whakamahana i tētahi teihana takirere JT o nāianei, ā, ko te tāpiri i te whakawhanui kāore pea e hiahiatia te tāuta i ētahi atu whakamahana, engari me whakanui ake i te rere o te wai wera.
Ngā pūnaha hinu whakahinuhinu me te hau hiri. E ai ki te kōrero i runga ake nei, ka taea e ngā kaiwhakawhanake te whakamahi i ngā hoahoa hiri rerekē, e hiahia ana pea ki ngā hinu whakahinuhinu me ngā hau hiri. Ki te tika, me pupuri te hinu whakahinuhinu i te kounga teitei me te parakore ina pā atu ki ngā hau tukatuka, ā, me noho tonu te taumata matotoru o te hinu ki roto i te awhe mahi e hiahiatia ana o ngā peera whakahinuhinu. Ko ngā pūnaha hau hiri he mea whakarite ki tētahi taputapu whakahinuhinu hinu hei ārai i te hinu mai i te pouaka peera kei uru ki te pouaka whakawhānui. Mō ngā tono motuhake o ngā taputapu e whakamahia ana i roto i te umanga warowaihā, ko ngā pūnaha hinu whakahinuhinu me te hau hiri he mea hanga kia rite ki ngā whakaritenga API 617 [5] Wāhanga 4.
Puku auau rerekē (VFD). Ina whakamahia te pūkaha hiko hei whakakā, ka whakakāhia he VFD hei whakarite i te tohu iahiko rerekē (AC) kia ōrite ki te auau o te taputapu. I te nuinga o te wā, he nui ake te whai huatanga whānui o ngā hoahoa e hangai ana ki ngā puku auau rerekē i ngā hoahoa e whakamahi ana i ngā pouaka miihini, i ētahi atu wāhanga miihini rānei. Ka taea hoki e ngā pūnaha e hangai ana ki te VFD te whakauru i te whānuitanga o ngā huringa tukanga ka hua ake he huringa i te tere o te rakau whakawhanui.
Tuku. Ko ētahi hoahoa whakawhanui ka whakamahi i te pouaka miihini hei whakaiti i te tere o te whakawhanui ki te tere kua whakaritea o te whakaputa hiko. Ko te utu o te whakamahi i te pouaka miihini he iti ake te whai huatanga katoa, nō reira he iti ake te putanga mana.
I te wā e whakarite ana i tētahi tono whakatau utu (RFQ) mō tētahi kaiwhakawhanake, me whakatau tuatahi e te kaihanga tukanga ngā āhuatanga whakahaere, tae atu ki ēnei mōhiohio:
He maha ngā wā ka whakaotihia e ngā miihini miihini ngā whakaritenga me ngā whakaritenga mō ngā miihini whakaputa whakaputa mā te whakamahi i ngā raraunga mai i ētahi atu mara hangarau. Tērā pea ko ēnei ngā mea e whai ake nei:
Me whakauru hoki ki ngā whakatakotoranga he rārangi tuhinga me ngā tuhi i whakaratohia e te kaihanga hei wāhanga o te tukanga tuku tono me te whānuitanga o te tuku, tae atu ki ngā tikanga whakamātautau e tika ana e hiahiatia ana e te kaupapa.
Ko ngā mōhiohio hangarau i whakaratohia e te kaihanga hei wāhanga o te tukanga tono me whakauru i ēnei āhuatanga:
Mena he rerekē tētahi āhuatanga o te tono mai i ngā whakatakotoranga taketake, me whakarato hoki e te kaihanga he rārangi o ngā rerekētanga me ngā take mō aua rerekētanga.
Kia tae mai he tono, me arotake e te tīma whakawhanake kaupapa te tono kia tutukihia ngā whakaritenga, me te whakatau mēnā he tika ngā rerekētanga hangarau.
Ko ētahi atu whakaaro hangarau hei whakaaroaro māu i te wā e arotake ana i ngā tono ko:
Hei whakamutunga, me whakahaere he tātaritanga ōhanga. Nā te mea ka rerekē pea ngā utu tīmatanga i ngā kōwhiringa rerekē, e taunakihia ana kia whakahaerehia he tātaritanga utu rere moni, he tātaritanga utu huringa ora rānei hei whakataurite i te ōhanga mō te wā roa me te hokinga mai o te haumitanga o te kaupapa. Hei tauira, ka taea te whakakore i te haumitanga tuatahi teitei ake i te wā roa mā te pikinga o te hua, te whakaiti rānei i ngā whakaritenga tiaki. Tirohia "Ngā Tohutoro" mō ngā tohutohu mō tēnei momo tātaritanga. 4.
Ko ngā tono whakaputa-turboexpander katoa e hiahia ana ki te tatau i te mana pūmanawa katoa hei whakatau i te nui katoa o te pūngao e wātea ana ka taea te whakahoki mai i roto i tētahi tono motuhake. Mō te whakaputa-turboexpander, ka tatauhia te pūmanawa mana hei tukanga isentropic (entropy pumau). Koinei te āhuatanga thermodynamic tino pai mō te whakaaro ki tētahi tukanga adiabatic hurihuri me te kore he waku, engari koinei te tukanga tika mō te whakatau tata i te pūmanawa pūngao tuturu.
Ka tatauhia te pūngao pūmanawa isentropic (IPP) mā te whakarea i te rerekētanga enthalpy motuhake i te tomokanga me te putanga o te turboexpander, me te whakarea i te hua mā te tere rere papatipu. Ka whakaatuhia tēnei pūngao pūmanawa hei rahinga isentropic (Whārite (1)):
IPP = ( hinlet – h(i,e)) × ṁ x ŋ (1)
ko h(i,e) te enthalpy motuhake me te whakaaro ki te pāmahana putanga isentropic, ā, ko ṁ te tere rere papatipu.
Ahakoa ka taea te whakamahi i te pūngao pūmanawa isentropic hei whakatau tata i te pūngao pūmanawa, ka uru te waku, te wera, me ētahi atu ngaronga pūngao tāpiri ki ngā pūnaha tūturu katoa. Nō reira, i te tatau i te pūmanawa mana tūturu, me whai whakaaro ki ngā raraunga whakauru tāpiri e whai ake nei:
I te nuinga o ngā tono turboexpander, ka whakawhāitihia te pāmahana ki te iti rawa hei ārai i ngā raruraru kāore e hiahiatia ana pērā i te tio o ngā paipa i kōrerotia i mua ake nei. I ngā wāhi e rere ana te hau māori, tata tonu te kitea o ngā hydrates, ko te tikanga ka tio te paipa i raro i te turboexpander, i te takirere throttle rānei ki roto, ki waho hoki mēnā ka heke te pāmahana putanga ki raro i te 0°C. Ka taea e te hanganga hukapapa te aukati i te rere, ā, i te mutunga ka kati te pūnaha ki te whakarewa. Nō reira, ka whakamahia te pāmahana putanga "e hiahiatia ana" hei tatau i tētahi horopaki mana pea e tino pono ana. Heoi, mō ngā hau pērā i te hauwai, he iti rawa te rohe pāmahana nā te mea kāore te hauwai e huri mai i te hau ki te wai tae noa ki te tae ki te pāmahana cryogenic (-253°C). Whakamahia tēnei pāmahana putanga e hiahiatia ana hei tatau i te enthalpy motuhake.
Me whai whakaaro anō hoki ki te whai huatanga o te pūnaha turboexpander. I runga i te hangarau e whakamahia ana, ka rerekē te whai huatanga o te pūnaha. Hei tauira, ko te turboexpander e whakamahi ana i te taputapu whakaiti hei whakawhiti i te kaha hurihuri mai i te tāpine ki te whakaputa hiko ka nui ake te ngaronga waku i te pūnaha e whakamahi ana i te taraiwa tika mai i te tāpine ki te whakaputa hiko. Ko te whai huatanga whānui o te pūnaha turboexpander ka whakaatuhia hei ōrau, ā, ka whakaarohia i te aromatawai i te pūmanawa mana tuturu o te turboexpander. Ka tatauhia te pūmanawa mana tuturu (PP) penei:
PP = (hinlet – hexit) × ṁ x ṅ (2)
Kia titiro tātou ki te whakamahinga o te whakaiti pēhanga hau māori. Kei te whakahaere a ABC, ā, kei te pupuri i tētahi teihana whakaiti pēhanga e kawe ana i te hau māori mai i te paipa matua, ā, ka tohatoha atu ki ngā kaunihera ā-rohe. I tēnei teihana, ko te pēhanga tomo hau he 40 pae, ā, ko te pēhanga putanga he 8 pae. Ko te pāmahana hau tomo kua whakamahanatia he 35°C, e whakamahana ana i te hau kia kore ai e huka te paipa. Nō reira, me whakahaere te pāmahana hau putanga kia kore ai e heke iho i te 0°C. I tēnei tauira ka whakamahia e mātou te 5°C hei pāmahana putanga iti rawa hei whakanui ake i te tauwehenga haumaru. Ko te tere rere hau rōrahi kua whakaritea he 50,000 Nm3/h. Hei tatau i te pūmanawa mana, ka whakaarohia e mātou ka rere katoa te hau mā te whakawhanui turbo, ā, ka tatau i te putanga mana mōrahi. Whakatauhia te pūmanawa putanga mana katoa mā te whakamahi i te tataunga e whai ake nei:
