Ngongo manometer – ngā raruraru me ngā otinga

Ngongo manometer – ngā raruraru me ngā otinga

1. E rua ngā momo wai e whakakīia ana tētahi ngongo manometer . Ko te mātotoru o te wai 1 ko ρ ₁ = 0.8 karamu.cm ^-3 , ā, ko te mātotoru o te wai 2 ko ρ ₂ = 1 karamu.cm ^-3 , ā, ko te teitei h ₁ = 10 cm, kātahi ka hia te teitei o h ₂.

Mōhiotia:

Te mātotoru o te wai 1 = 0.8 karamu.cm ^-3

Te mātotoru o te wai 2 = 1 karamu.cm ^-3

Teitei 1 = 10 henemita

E hiahiatia ana: Teitei 2

Rongoā:

2. E 50 henemita te teitei o te wai, ā, e 30 henemita te teitei o ētahi atu wai. He aha te mātotoru o ētahi atu wai?

Mōhiotia:

Whakaterenga na te kaha o te kaha (g) = 10 m/s²

Te teitei o te wai (h1 ₎ = 50 cm

Te mātotoru o te wai (ρ ₁ ) = 1.00 x 103 ^kg /m3 ⁼ 1000 kg/ ^m3

Teitei o tētahi atu wai (h ₂ ) = 30 cm

E hiahiatia ana: Te mātotoru o tētahi atu wai.

Rongoā:

pa + ρ ₁ gh ₁ = pa + ρ ₂ gh ₂

1. He aha te manometer? WhakautuHe taputapu te manometer hei ine i te pēhanga o ngā hau me ngā wai. Ko te tikanga, ka ine i te rerekētanga pēhanga i waenga i te wai i roto i te manometer me te āhuarangi e karapoti ana, i tētahi atu wai rānei.
2. He pēhea te mahi a te manometer ngongo-U māmā? WhakautuKo te mahi a te manometer ngongo-U i runga i te whakataurite i te pēhanga e tukuna ana e te pou wai ki te pēhanga o te wai e inehia ana. Mena he rerekētanga te pēhanga, ka neke te pou wai ki tētahi tūranga hou, ā, ka taea te whakamahi i te rerekētanga teitei hei whakatau i te rerekētanga pēhanga.
3. He aha ngā wai e whakamahia whānuitia ana i roto i ngā manometa? WhakautuKo ngā wai manometri noa ko te konukōre, te wai, me te hinu. Ko te kōwhiringa wai e whakawhirinaki ana ki te whakamahinga, te aro e hiahiatia ana, me te whānuitanga o ngā pēhanga hei ine.
4. He aha i whakamahia pinepine ai te konukōre i roto i ngā manometer ahakoa tōna paitini? WhakautuHe matotoru te mercury, ā, he taumaha motuhake teitei, e āhei ai te teitei o ngā pou poto ake me te hoahoa manometer iti ake mō te rerekētanga pēhanga ōrite. Kāore hoki e whakamakuku i te karāhe, kia tika ake ai ngā pānui. Heoi, me āta whakahaere me te whai whakaaro ki te haumaru o te taiao mō tōna āhua paitini.
5. He aha te rerekētanga i waenga i te manometer tuwhera me te manometer kati? WhakautuHe tohu mita tuwhera kei te tuwhera tetahi pito ki te āhuarangi, ā, ka ine i te rerekētanga pēhanga i waenga i te wai e whakamatautauria ana me te pēhanga āhuarangi. Ko te tohu mita kati, i tetahi atu ringa, he hiri tetahi pito, he maha ngā wā ka whakamahia he korehau, he pēhanga tohutoro rānei e mōhiotia ana, ā, ka ine i te pēhanga tino o te wai.
6. Me pēhea te whakamahi i te manometer hei ine i te tere? WhakautuMā te whakamahi i te mātāpono o te whārite a Bernoulli me te ngongo Pitot-pūmau, ka taea te ine i te pēhanga hihiri (e pā ana ki te tere) me te pēhanga pūmau. Ko te rerekētanga teitei i roto i te manometer e rite ana ki te pēhanga hihiri, ka taea te huri ki te tere.
7. He aha te mea nui kia poutū te ngongo manometer i te wā e ine ana? WhakautuMā te pupuri i te ngongo manometer kia poutū ka whakarite kia heke tika te taumaha o te wai manometer, ā, ko te teitei o te pou wai e tohu tika ana i te rerekētanga pēhanga. Mā te honga ka puta he hapa i roto i te pānui.
8. He aha te rerekētanga o te manometer rerekētanga mai i te manometer ngongo-U noa iho? WhakautuHe mea hanga te manometer rerekētanga hei ine i te rerekētanga o te pēhanga i waenga i ngā pūwāhi e rua i roto i tētahi pūnaha wai, engari he maha ngā wā ka ine te manometer ngongo-U noa i te rerekētanga o te pēhanga i waenga i te wai me te āhuarangi.
9. He aha ngā herenga o te whakamahi i te manometer? WhakautuHe taputapu e whakawhirinaki ana ki te kaha ā-papatipu ngā manometer, nō reira me noho poutū tonu. Kāore pea i te pai mō ngā ine pēhanga tino teitei (i runga i te wai manometer e whakamahia ana), ā, ka pāngia pea e ngā huringa pāmahana ka pā ki te mātotoru o te wai.

10. He aha te manometer "momo-pūnga"? Whakautu : Kotahi te waewae o te manometer momo-pūnga he nui ake te whānui e kiia nei ko te "pūnga". Kāore te wai i roto i tēnei pūnga e piki ake, e heke iho rānei i ngā huringa pēhanga, ā, ko te pānui ka whakawhirinaki noa ki te huringa teitei o te waewae whaiti. Mā tēnei hoahoa ka whakanui ake i te aro me te ngāwari o te pānui o te manometer.
