He maha ngā mita rere e whai hua ana ki te whakapai ake i te pai o te pūnaha, te tika, tae atu ki te pono, kia roa ai te wā. He mea nui kia tirohia ngā āhuatanga rerekē o ia momo, me pēhea hoki e whakaoti ai i ngā hiahia nui o te ahumahi. Kimihia he momo mita rere hei whakatutuki i ngā hiahia motuhake.
Ngā Momo Mita Rere
Mita rere papatipu
Hemita rere papatipu, e mōhiotia ana ko te mita rere ā-inertia, e whakamahia ana hei ine i te tere rere o te papatipu o te wai e rere ana i roto i te ngongo. Ko te papatipu o te wai e rere ana i tua atu i te pūwāhi pumau mō ia wā ka kiia ko te tere rere o te papatipu. Ka ine te mita rere papatipu i te papatipu, kaua ki te rōrahi mō ia wā (hei tauira, kgs ia hekona) e tukuna ana mā te taputapu.
Ngā mita rere Coriolise kiia ana ko ngā mita rere tino tika ka taea te whakahoki anō i tēnei wā. Ka tukuna e rātou he wai ki roto i ngā ngongo wiri, ā, ka aroturuki i ngā huringa o te nekehanga o te wai. Ka puta he takahuri iti, he rerekē rānei te āhua o ngā wai i roto i ngā ngongo wiri. He rite tonu te takahuri me te rerekē o aua āhua ki ngā tere rere papatipu. Ka mahi ngā mita Coriolis i roto i ngā mea e rua.te ine i te papatipu me te mātotoru, he maha ngā whakamahinga i roto i ngā momo mahi pēnei i te matū, te hinu, me te hau. Ko ā rātou mahi tino pai i roto i te tika me te whakamahinga whānui ngā take matua mō tō rātou rongonui i roto i ngā pūnaha ahumahi matatini.
Momo Ārai
Ngā mita rere pēhanga rerekē (DP)kua whakatikatikaina kia rite ki ngā whanaketanga o ngā hiahia ahumahi hou, ā, koinei tonu te kōwhiringa pono rawa atu mō te aroturuki me te ine i te rere. Ka inehia te rerekētanga pēhanga i runga i te kaupapa o te whanaungatanga i waenga i te rerekētanga pēhanga ka puta i te wa e rere ana te wai i roto i ngā taputapu whakawhāiti me ngā tere rere. Ko te taputapu whakawhāiti he huānga whakaheke ā-rohe kua tāutahia ki roto i te paipa. Ko ngā mea e whakamahia whānuitia ana kongā pereti kōhao, ngā pūweromengā ngongo venturi,e whakamahia whānuitia ana i roto i te ine me te whakahaere i ngā tukanga ahumahi.
A mita horahanga taurangiMā te ine i te rere o te wai e whiti ana i te horahanga wāhanga o te taputapu ka rerekē te urupare ki te rere. Ko ētahi pānga ine e tohu ana i te tere. Kei te wātea te mita hurihuri, he tauira o te mita horahanga rerekē, mō te whānuitanga o ngā wai, ā, e whakamahia whānuitia ana me te wai, te hau rānei. Ko tētahi atu tauira ko te kōhao horahanga rerekē, ka panaia e te rere o te wai e tukuna ana mā te kōhao he pūwero pūmau.
Ine Rere Whakamārama
Temita rere o te tāpineKa hurihia te mahi ā-pūkaha ki tētahi tere rere e taea te pānui e te kaiwhakamahi. pērā i te gpm, te lpm, me ētahi atu. Ka whakatakotoria te wira tāpine ki te ara o te rerenga wai kia haere katoa ai te rere huri noa i a ia. Kātahi ka pā te wai rere ki ngā mata o te tāpine, ka puta he kaha ki runga i te mata, ka panaia te rotor kia neke. He rite te tere o te tāpine ki te tere wai ina tae ki tētahi tere hurihuri pumau.
Ine Rere Hikohiko
Temita rere aukume, e mōhiotia ana ko "mita makasini" rānei "hikohiko", whakamahia he āpure ine i whakamahia ki te ngongo ine, ka puta he rerekētanga pūmanawa i roto i te ōwehenga ki te tere rere poutū ki ngā rārangi rere. Ka mahi ēnei mita i runga i te Ture a Faraday mō te Whakaoho Hikohiko, e whakamahia ana he āpure ine ki te wai. Kātahi ka taea te whakatau i te tere rere mā te ngaohiko hua i inehia. Ko te otinga matua mō ngā ahumahi e pā ana ki ngā wai paru, waikura, whakakoi rānei. Mō ngā kaupapa o te tika me te roa,ngā mita rere aukumee whakamahia ana i roto i te maimoatanga wai, te tukatuka matū, tae atu ki te hanga kai me te inu.
Hemita rere ultrasonicKa ine i te tere o ngā wai mā te ultrasound hei tatau i te rere o te rōrahi. Ka taea e te mita rere te ine i te tere toharite i te ara o te hihi ultrasound e tukuna ana mā roto i ngā whakawhiti ultrasonic. Tātaihia te rerekētanga o te wā whakawhiti i waenga i ngā pāorooro o te ultrasound ki raro ki roto, ki te taha rānei o te ahunga rere, ine rānei i te nekehanga auau i runga i te Pānga Doppler. Haunga te āhuatanga oro o te wai, ko te pāmahana, te mātotoru, te matotoru me ngā matūriki iri he mea anō hoki e pā ana ki temita rere tino.
Hemita rere awhiowhioE mahi ana i runga i te kaupapa "von Kármán vortex", e aroturuki ana i te tere rere o te wai mā te ine i te auau o ngā awhiowhio. I te nuinga o te wā, he rite tonu te auau o ngā awhiowhio ki te tere rere. Ka whakaputahia e te huānga piezoelectric i roto i te pūoko he tohu utu tauutuutu me te auau rite ki te awhiowhio. Kātahi ka tukuna taua tohu ki te taputapu whakakī rere atamai hei tukatuka atu.
Ngā mita rere ā-mīhini
Ka inehia e te mita nekehanga pai te rōrahi o ngā wai e rere ana i roto i tētahi oko pērā i te peere, i te uati mutu rānei. Ka taea te tatau i te tere rere mā te ōwehenga o te rōrahi me te wā. Me whakakī tonu me te whakawātea i ngā peere kia taea ai te ine tonu. Ko ngā mita piston, ngā mita taputapu porowhita me te mita kōpae nuting he tauira katoa o ngā mita nekehanga pai.
Mai i ngā mita rere ā-mīhini maha-whakamahinga ki ngā mita Coriolis me ngā mita ultrasonic tino tika, kua whakaritea ia momo kia tutuki ai ngā hiahia ahumahi motuhake. Ahakoa me whakahaere e koe ngā hau, ngā wai, ngā mamaoa rānei, he otinga kei reira māu. Me mahi i te taahiraa e whai ake nei ki te whakapai ake i te pai o tō pūnaha mā te rapu tohutohu a te tohunga.Whakapā maii tēnei rā, mō tētahi whakatau utu kore utu, kāore he herenga, ā, mā mātou koe e āwhina ki te kimi i te mita rere tino tika mō tō mahi!
