Ka mahi ngā mahanga mamaoa mīhini mā te whakaaro ki te rerekētanga o te mātotoru i waenga i te mamaoa me te waipū. Ka haere tonu rātou i roto i ngā rahinga nui o te waipū, ā, he pai mō te whānuitanga o ngā mahi tukatuka. Ko ētahi o ēnei ko ngā mahanga mamaoa pōrewai me ngā mahanga mamaoa peere hurihuri.

Ngā Mahanga Kohu Pōro (Ngā Mahanga Kohu Ā-ringa)

Ka mahi ngā mahanga pōtakataka mā te rongo i te rerekētanga o te mātotoru i waenga i te mamaoa me te waikeri. Mō te mahanga e whakaaturia ana i te ahua ki te taha matau (he mahanga pōtakataka me te takirere hau), ka piki ake te waikeri ina tae te waikeri ki te mahanga, ka hiki ake te takirere i tōna nohoanga, ā, ka heke te hau.

Ka whakamahia e ngā mahanga hou ngā pūhaumāota whakahaere, e whakaaturia ana i te whakaahua ki te taha matau (Ngā Mahanga Whakarewa me ngā Pūhaumāota Whakahaere). Mā tēnei ka taea te rere o te hau tuatahi, ā, ka taea hoki e te mahanga te whakahaere i te waikeri.

Ka whakamahia e te pūhaumāota aunoa tētahi huihuinga pūwero pēhanga taurite, he rite ki te mahanga mamaoa whakahaere, kei roto i te wāhi mamaoa i runga ake i te taumata waipūhau.

Ina tukuna te hau tuatahi, ka noho kati tonu kia kohia rā anō te hau, ētahi atu hau rānei kāore e taea te whakapūpū i te wā e whakamahia ana i te tikanga, ā, ka whakatuwheratia mā te whakaheke i te pāmahana o te ranunga hau/korohū.

Ko te painga anō o te pūhaumāota whakahaere ko te whakapai ake i te kaha o te hauhautanga i te wā e tīmata makariri ana.

I ngā wā o mua, mēnā he hama wai kei roto i te pūnaha, he ngoikore te pūhaumāota whakahaere. Mēnā he kino te hama wai, ka pakaru pea te pōro. Heoi, i roto i ngā mahanga pōtakataka hou, ka taea e te pūhaumāota te noho hei kāpene maitai kore waikura kiato, tino kaha, ā, mā ngā tikanga whakarewa hou e whakamahia ana ki te pōro ka tino kaha, ka pono hoki te pōtakataka katoa i roto i ngā āhuatanga hama wai.

I ētahi wā, ko te mahanga whakamahana pōrewarewa te mea e tata ana ki te mahanga mamaoa tino pai. Ahakoa te rerekētanga o te pēhanga mamaoa, ka tukuna wawe tonu i muri i te putanga mai o te wai whakapūhau.

Ngā Painga o ngā Mahanga Kohu Whakamahana Whakarewa

Ka tukuna tonutia e te mahanga te wai whakapūhau i te pāmahana mamaoa. Nā tēnei ka waiho hei whiringa matua mō ngā tono kei reira te tere whakawhiti wera o te mata wera kua whakaratohia.

He pai hoki te whakahaere i ngā kawenga wai whakapūkara nui, māmā rānei, ā, kāore e pāngia e ngā piki me ngā heke ohorere o te pēhanga, o te rere rānei.

Mēnā kei te tāutahia he pūhaumāota aunoa, ka wātea te mahanga ki te whakaputa hau.

Mō tōna rahi, he kaha whakaharahara tēnā.

Ko te putanga me te takirere tuku raka mamaoa anake te mahanga e tino tika ana mō tetahi raka mamaoa e ātete ana ki te hama wai.

Ngā Huakore o ngā Mahanga Mamao Whakamahana Whakarewa

Ahakoa kāore i te tino pāngia e ngā mahanga peere hurihuri, ka taea e ngā mahanga pōtae te pakaru i ngā huringa āhua kino, ā, ki te tāutahia ki tētahi wāhi e kitea ana, me whakaroa te tinana matua, me/ranei me tāpiri atu ki tētahi mahanga iti tuarua hei whakarite i te wai.

Pērā i ngā mahanga mīhini katoa, me whai hanganga ā-roto tino rerekē kia taea ai te whakahaere i runga i te awhe pēhanga rerekē. Ko ngā mahanga i hangaia hei mahi i ngā pēhanga rerekē teitei ake he iti ake ngā kōhao hei taurite i te pōrewarewa o te pōrewarewa. Mena ka pāngia te mahanga e te pēhanga rerekē teitei ake i te mea i whakaarohia, ka kati, ā, kāore e puta te waipū.

Ngā Mahanga Kohu Pākete Hurihuri (Ngā Mahanga Kohu Ā-ringa)

(i) Ka piko te oko, ka kumea te takirere mai i tōna nohoanga. Ka rere te wai whakapūhau i raro i te raro o te peere, ka whakakī i te peere, ā, ka mimiti atu mā te putanga.

(ii) Ka mānu te oko i te taenga mai o te mamaoa, kātahi ka piki ake, ka kati te putanga.

(iii) Ka noho kati te mahanga kia mimiti, kia pupuhi rānei te mamaoa i roto i te peere mā roto i te kōhao hau ki te tihi o te tinana mahanga. Kātahi ka totohu, ka hutia te nuinga o te takirere mai i tōna nohoanga. Ka ringihia te wai whakapūpū kua kohia, ā, ka haere tonu te huringa.

I roto i te (ii), mā te hau e tae atu ki te mahanga i te tīmatanga ka puta te pūmau o te peere, ā, ka kati hoki te takirere. He mea nui te putanga o te peere kia puta te hau ki te tihi o te mahanga hei tukunga atu mā te nuinga o ngā nohoanga takirere. Nā te iti o ngā kōhao me ngā rerekētanga pēhanga iti, he puhoi te putanga o te hau ki ngā mahanga. I taua wā anō, me haere mā roto (ā, ka moumou) i tētahi nui o te mamaoa kia mahi ai te mahanga i muri i te whakakorenga o te hau. Mā ngā putanga whakarara e tāutahia ana i waho o te mahanga ka whakaiti i te wā tīmatanga.

Ngā Painga oNgā Mahanga Kohu Pākete Hurihuri

I hangaia te mahanga mamaoa peere hurihia hei ātete i te pēhanga teitei.

He rite ki te mōunu mamaoa whakamahana tere, he tino ātete ki ngā āhuatanga o te hama wai.

Ka taea te whakamahi i runga i te raina mamaoa wera rawa, me te tāpiri i tētahi takirere tirotiro ki te awaawa.

He wā tuwhera te aratau rahunga, nō reira he haumaru ake mō ngā tono e hiahia ana ki tēnei mahi, pērā i te rerenga wai o te tāpine.

Ngā Huakore o ngā Mahanga Kohu Pākete Hurihuri

Nā te iti o te pūaha i te tihi o te peere, ka puhoi noa te putanga o te hau i tēnei mahanga. Kāore e taea te whakanui ake i te pūaha nā te mea ka tere rawa te puta o te mamaoa i te wā e whakamahia ana.

Me nui te wai i roto i te tinana o te mahanga hei hiri i te taha o te peere. Mēnā ka ngaro te hiri wai o te mahanga, ka maumauria te mamaoa mā te takirere putanga. He maha ngā wā ka puta tēnei i ngā mahi e heke ohorere ana te pēhanga mamaoa, ka "pupuhi" ētahi o te wai whakapūpū i roto i te tinana o te mahanga hei mamaoa. Ka ngaro te kaha o te pūmau o te oko, ā, ka totohu, ka taea ai te mamaoa hou te haere mā roto i ngā kōhao wai. Kia tae rā anō te wai whakapūpū ki te mahanga mamaoa, ka taea ai te hiri anō i te wai hei ārai i te maumau mamaoa.

Mena ka whakamahia he mahanga peere hurihuri i roto i tētahi mahi e tika ana kia puta he rerekētanga o te pēhanga o te tipu, me tāuta he takirere tirotiro ki te rārangi tomo i mua i te mahanga. Ka taea te rere noa o te mamaoa me te wai i te ahunga kua tohua, engari kāore e taea te rere whakamuri nā te mea kua pēhia te takirere tirotiro ki tōna nohoanga.

Ka taea e te pāmahana teitei o te mamaoa wera rawa te whakararu i te hiri wai o te mahanga peere hurihuri. I roto i ēnei āhuatanga, me whakaaro he mea nui te takirere ārai i mua i te mahanga. He iti noa iho ngā mahanga peere hurihuri e hangaia ana me te "takirere ārai" whakauru hei paerewa.

Ki te waihotia he mahanga peere hurihuri kia tata ki raro i te kore, ka pakaru pea i te huringa āhua. Pērā i ngā momo mahanga miihini rerekē, ka taea e te whakamarumaru tika te wikitoria i tēnei ngoikoretanga mena kāore i te tino kino ngā āhuatanga. Mena kei raro rawa i te kore ngā āhuatanga taiao e tumanakohia ana, he maha ngā mahanga kaha me āta whakaarohia kia pai ai te mahi. Mō te waikeri matua, ko te mahanga hihiri thermos te whiringa matua.

Pērā i te mahanga pōrewarewa, kua hangaia te whakatuwheratanga o te mahanga peere hurihuri kia uru ki te rerekētanga pēhanga mōrahi. Mena ka pāngia te mahanga e te pēhanga rerekētanga teitei ake i te mea e whakaarohia ana, ka kati, ā, e kore e puta te wai whakapūhau. Kei te wātea i roto i te whānuitanga o ngā rahi kōhao hei taupoki i te whānuitanga o ngā pēhanga.
