I roto i te mara o te ine i te rere o te wai, e rua ngā otinga e whakamahia whānuitia ana, arā, ngā mita wai miihini me ngā mita wai hikohiko, he rerekē ngā āhuatanga o ia mita, o ia mita e hāngai ana ki ngā hiahia tono rerekē. He mea nui te mārama ki ō rāua rerekētanga hei whiriwhiri i te taputapu tika i roto i ngā horopaki mai i ngā whare noho ki ngā whare ahumahi.
Ko ngā mita wai mīhini, te kōwhiringa tuku iho, e mahi ana i runga i tētahi kaupapa māmā engari kua roa e whakamatautauria ana. E whakawhirinaki ana rātou ki ngā wāhanga neke - pērā i ngā impeller, i ngā turbine rānei - e peia ana e te kaha nekeneke o te wai e rere ana. I a te wai e haere ana i roto i te mita, ka hurihia te impeller o roto, ā, ka tukuna tēnei hurihanga mā te pūnaha taputapu ki tētahi kaute e whakaatu ana i te katoa o te wai e pau ana. Kua neke atu i te rautau te whakapai ake i tēnei hoahoa, ā, ka hua ake he hangarau pakari me te pono. Ko tētahi o ōna painga nui ko te whai huatanga o te utu; he iti noa ngā utu hanga me te tāutanga, koia te whiringa matua mō te ine wai kāinga puta noa i te ao. Hei tāpiri, kāore e hiahiatia he pūtake hiko o waho e ngā mita mīhini, nā te mea ka whakamahia tika te kaha mai i te rere o te wai. Mā tēnei āhuatanga "whaiaro" ka taea e rātou te mahi i ngā wāhi tawhiti, i ngā wāhi rānei he putunga hiko kore pumau.
Heoi, he nui ngā ngoikoretanga o ngā mita wai miihini. Ka ngāwari te pakaru me te haehae o ō rātou wāhanga neke i roto i te wā, inā koa ka pāngia e te wai kei roto ngā poke pēnei i te onepu, te waikura, te unahi rānei. Ehara i te mea ka whakaiti noa i te tika o te inenga tēnei pakaru engari ka arahi pea ki te aukati, me tiaki, me whakakapi rānei i ia wā. Heoi anō, he kuiti te ōwehenga hurihanga, ko te tikanga he uaua ki te ine tika i ngā rerenga wai tino iti me te tino teitei. Hei tauira, ko ngā turuturu iti, ko te whakamahinga wai iti rānei, ka kore pea e kitea, ko ngā wā rere nui ka hua ake he hapa ine nui. Ko tētahi atu ngoikoretanga ko te ngaronga pēhanga: ka hangaia e te hanganga miihini o roto he ātete ki te rere o te wai, ka pā ki te whai huatanga o ngā pūnaha tuku wai.
He rerekē, ko ngā mita wai hikohiko he huarahi kē atu e matatau ake ana, e ahu mai ana i te hangarau. E hangai ana ēnei ki te Ture a Faraday mō te whakapūtanga hikohiko. Ka hangaia he papa aukume huri noa i te ngongo ine kore-aukume o te mita e te koiri whakaoho. Ina rere te wai kawe i roto i tēnei papa aukume, ka tapahia e ia ngā rārangi kaha aukume, ka puta he kaha hikohiko (EMF) i roto i ngā irahiko e mau ana ki ngā pakitara o te ngongo. Ko te rahi o tēnei EMF he rite tonu ki te tere rere o te wai, e āhei ai te mita ki te tatau me te whakaatu i ngā tere rere me te tino tika.
He maha ngā painga matua o ngā mita hiko aukume ki ō rātou hoa miihini. Kāore he wāhanga neke o roto, e whakakore ana i ngā raruraru o te kakahu, te aukati, me te ngaronga pēhanga. Nā tēnei hoahoa hoki ka tino ātete rātou ki ngā poke o te wai, ā, he mea pai mō te ine i te wai mata, te wai para, te wai tukatuka ahumahi rānei. He whānui rawa te ōwehenga hurihanga (he maha ngā wā 100:1, neke atu rānei), e āhei ai te ine tika i ngā turuturu iti me ngā rerenga nui. Hei tāpiri, ka hono pai ki ngā pūnaha atamai, e tautoko ana i te aroturuki raraunga wā-tūturu, te pānui mamao, me te kimi turuturu—ngā āhuatanga nui mō te whakahaere wai atamai me ngā rohe ine rohe (DMA).
Heoi anō, he herenga anō ō ngā mita hikohiko. Ka taea anake e rātou te ine i ngā wai kawe hiko; nā ngā matū kore-kawe hiko pērā i te wai māori, te hinu rānei, ka kore ai e whai hua. He nui ake te utu tīmatanga i te utu o ngā mita miihini, ā, ka waiho hei arai mō te whakatinanatanga o ngā whare noho nui. Me whai pūtake hiko o waho tonu hoki hei whakaputa i te papa aukume me te tukatuka i ngā tohu, ka whakawhāiti i tō rātou whakamahinga i ngā wāhi kāore he hiko pono.
Hei whakamutunga, ko te whiriwhiri i waenga i ngā mita wai ā-ringa me ngā mita wai hikohiko e whakawhirinaki ana ki ngā whakaritenga tono motuhake. He tino pai ngā mita wai ā-ringa i roto i ngā wāhi noho iti te utu, he iti te tiaki, he iti nei te urunga hiko. I taua wā, ko ngā mita hikohikohiko te kōwhiringa pai mō ngā tukanga ahumahi, te maimoatanga wai para, me ngā whatunga wai atamai e hiahia ana ki te tika teitei, te whānuitanga rere whānui, me ngā āheinga aroturuki atamai. Mā te paunatia ngā āhuatanga pēnei i te utu, te tika, ngā hiahia tiaki, me ngā āhuatanga wai, ka taea e ngā kaiwhakamahi te whiriwhiri i te mita e pai ana ki ā rātou whāinga whakahaere.
