Inenga Aneroid: he pūrere hoki ine pēhanga kōhauhau

He aha te mea he inenga? huaina ana tēnei wā hangarau te he pūrere mō te ine pēhanga kōhauhau. Ko te whakamahia tino whānui e rua momo o barometers. inenga mēkuri whakamahia mō te ine pēhanga kōhauhau matua i runga i ngā teihana METEOROLOGICAL.
Ko reira atu cumbersome, engari homai me nui tika inenga, na pūtaiao, me te hoatu hiahia ki a ia. Inenga o tenei momo i whakaaro, ka hanga e te pūtaiao Itari Evangelista Torricelli i 1644. Ko tōna parau tumu whakahaere - whakataurite i te tīwae o te mēkuri ki rangi pou. Nā ki te nui te mātotoru o te mēkuri teitei tīwae he iti rawa (ina te mea te reira e te pēhanga kōhauhau - 760 mmHg, e te tikanga ki te kaha taua fakamālohii te rangi kōhauhau i te wāhi ruri).

Aneroid inenga - he pūrere matatini ake. Ahakoa i whakaarohia te whakaaro pūrere tata tukutahi ki te tenenga o te inenga mēkuri (i te reira i roto i te taua whitu-rau German pūtaiao Gotfrid Leybnits), engari riro te whakatinanatanga mahi o te whakaaro o te German nui tau e rua anake rau. I roto i te 1847, he mataaro pūkaha pūmanawa French Lucien vidi i hanga inenga aneroid tuatahi o te ao. He aha te mea te parau tumu o tona mahi?

te ingoa i te inenga i "aneroid", e he anhydrous. hanga ana tēnei wā ko rite ki te haapapu e kore ko te mea i roto i te te whakamahi kahore inu, pērā mēkuri inenga, te huānga pūoko ko ai te whakarewa wai.
hiritia te huānga aneroid Tārewa te pouaka i hanga o rauemi kowakawaka, i, ka whakanui ake whakaiti i te pēhanga hau paku kōpeke whakawhānui ranei ranei. hua pūnaha ringa i roto i te kaupapa o te pere, i te mea āta he tauine puta tohu te pēhanga kōhauhau i roto i mitamano o konuoi.

e te mea he, kahore uaua, a taea te hanga aneroid inenga i te taumata o te whanaketanga hangarau rite nga wa Torricelli me i mua. He aha e kore i tupu i te reira? Te nuinga pea, i konei te whakatangihanga a ia te tūranga o te huinga o te maha āhuatanga. Tuatahi, me te tuatahi - ko te kore o te hiahia mo te mea taua i te wa. I roto i te meka, rite te pūtaiao o te huarere kōhungahunga me te ti'aturiraa iti o ngā rerekētanga pēhanga kōhauhau me te rangi i mohio anake e pūtaiao i te wa. I tua atu, pea te tūranga takaro e te kore o te rauemi e tika ana mō ngā pouaka kowakawaka (Me whai ia elasticity manakohia me te totoro i roto i te mahi roa). Ki te whanaketanga o te pūtaiao, me te tikanga tuatahi, me te tuarua e kore ārai i te hanganga o te aneroid.

I muri i te tenenga o Lyuena vidi timata aneroid inenga ki te rere i roto i nga whare tūmataiti me whaitua. He ko ara he ahua o te ahua: te aroaro o tenei mea i roto i te whare fakamamafa'i mana pāpori, me te hinengaro o te ope. he tangata taua, i roto i ngā hou, i whakaaro "matatau".

Ka rite ki te whakatamarikitanga o te ngahuru te ao pūnaha (SI), te nuinga o nga whenua aneroid kua meinga tauine māka tauine kīnaki, wāhi e tohua ana te pēhanga e kore anake i roto i mitamano o konuoi (kore te mea he kotahi pūnahanaha tenei), engari ano hoki i roto i Pascals. He he he tauine māka o aneroid i tutaki. Pae - he wae pūnaha-kore hoki, āhua rite ki te kotahi huru. I te tahi taime whanganga pēhanga i roto i te pae, ko te atu watea atu i roto i mitamano o mēkuri, i roto i ngā wae pūnaha ranei.

Heoi, kua te peu o ine te pēhanga kōhauhau i roto i mitamano o konuoi kua tino kaha. Ahakoa inaianei, matapae huarere pēhanga kōhauhau tohua i roto i enei wae pūnaha-kore.
