Te Pūtaiao i Muri i te Kaukau Whirlpool
Kua roa ngā kaukau whirlpool e whakanuia ana mō tō rātou kaha ki te whakarato i te whakangā me te whakamarie, ā, ko te ngako o tō rātou ataahua whakaora ko ngā jet mirimiri. Ko te mahi a ēnei jet he kaupapa whakamīharo e ahu mai ana i ngā mahi wai, e tuku ana i te wheako whakaora wai whakaora.
Ko te mahi a ngā jet mirimiri e aro ana ki ngā mātāpono matua e rua: te mātāpono a Bernoulli me te pānga Venturi. Ina whakahohehia te kaukau whirlpool, ka kukumehia e te pūnaha papu te wai mai i te kaukau ka panaia mā roto i ngā jet kua whakanohoia ki ngā wāhi rautaki. I te rere o te wai mā roto i ngā pūaha whaiti o ngā jet, ka piki ake tōna tere i te mea ka heke iho tōna pēhanga, e ai ki te mātāpono a Bernoulli.
Nā te hekenga o te pēhanga ka puta he pānga momi, ka nui ake te wai e kumea ana ki roto i ngā pūaha o te wai. Nō reira, ka puta te wai i ngā wai i te tere teitei, ka puta he rere pōrearea i roto i te kaukau. Nā tēnei rere pōrearea e whakarato ana i te wheako mirimiri whakahauora.
Ka pā ngā rerenga wai pēhanga teitei mai i ngā awa ki te kiri, ka puta he kare ā-roto o te whakangā me te whakamarie. Ka whakaoho tēnei mahi pāorooro i te rere o te toto, ka whakatairanga i te rere o te toto ki ngā uaua kua pēhia, kua mamae rānei. Ka āwhina te whakapai ake i te rere o te toto ki te whakaora me te whakangā o ngā uaua, ka whakaora i te mamae me te taumahatanga.
He maha ngā kaukau kaukau he pūwero whakarerekētanga, e āhei ai ngā kaiwhakamahi ki te whakarite i tā rātou wheako mirimiri. Mā te whakarerekē i te ahunga me te kaha o ngā pūwero, ka taea e ngā kaiwhakamahi te aro atu ki ngā wāhi motuhake o te tinana e hiahia ana kia nui ake te aro, kia nui ake rānei te whakaora. Mā tēnei whānuitanga o ngā whakamahinga ka whakarei ake i ngā painga rongoā o ngā kaukau kaukau, e whakatutuki ana i ngā hiahia me ngā manakohanga takitahi.
Haunga ngā painga ā-tinana, ka pā nui te wai whakaora e tukuna ana e ngā wai wera kaukau ki te oranga hinengaro. Mā te whakakotahitanga o te wai mahana me ngā wai mirimiri ka hangaia he taiao whakamarie e āwhina ana ki te whakamarie i te hinengaro me te whakaiti i te ngenge hinengaro. He huarahi whānui tēnei ki te whakangā, e aro ana ki te tinana me te hinengaro.
Ko te tikanga, ka whakamahia e ngā pū mirimiri i roto i ngā kaukau whirlpool te mana o ngā mahi wai hei tuku i tētahi wheako whakaora ahurei. Mā te whakakotahitanga o te mātāpono a Bernoulli, te pānga Venturi, me ngā pūwero ka taea te whakarite, ka tukuna e ēnei pū he whakamarie me te whakangā, ka huri i te rumaki ngāwari hei rerenga whakaora.
