Kaha wera motuhake o te rangi. ngā āhuatanga ōkiko o te matū

te rangi a tawhio noa tatou e whai wāhi nui i roto i te ora o te kaiao koiora e noho ana i te whenua ao. Ko e pā ana mahi a te tangata te ki te momo o ngā tukanga hangarau, tāutuhia te taonga i roto i te kāwai o ngā haurehu tū nui. I waiho i raro ia ki te ako tino i runga i te tumu parau o ngā āhuatanga ōkiko. I roto i te ngā, i tāutuhia mau taata i ngā āhuatanga o te rangi, etahi o ratou āhuatanga me ririki.

Ko te uaua o te mahi ki te rangi ko e ko te reira he taonga heterogeneous, a ka he te otinga o te tau nui o ngā wāhanga. Ko te taua ahua katoa o te pūmautanga o ona mema o he reira.

tunu Natural hau faufaa (rangi) Kei te huinga nui pūmau o kai. Ki te rā, i te ōrau e whai ake nei ratou: hauota noho 78 ōrau hāora - 20, te hauhā - 0.03 ōrau. Ko te mamaoa me te tahi atu hau, me te ara matūriki totoka noho e pā ana ki te hawhe ōrau. kaha wera motuhake o te rangi, ko te ti'aturi e kore anake i runga i ētahi atu āhuatanga tinana, engari rerekē i runga i te ihirangi ā-(hanganga) hau.

I pau te kohinga me te tātari o ngā raraunga i runga i te āhuatanga thermodynamic o rangi rōpū mahi taiwhanga nui o te ao. Ēnei rangahau mai i te mutunga o te rau tau XIX, me te kaha tonu ki tenei ra. E whakamahia ratou hua i roto i te tātai o te whānui o te pūngao me te rangi wehenga otaota, mihini mo te ahumahi matū, me ētahi atu pūrere momo.

wera motuhake o te rangi, ko te uara e whakatau te nui o te pūngao wera e me pau ki tetahi manokaramu o te hau te huri tona pāmahana i tetahi tohu (Kelvin). Homai te fakafalala o te mea i mua i tenei uara i runga i ngā āhuatanga maha mō ngā take engineering he kauwhata rerekē me tepu. tohu ratou pehea te wera motuhake o te rangi i runga i te pāmahana haumākū ranei.

Hoki pai te māramatanga o tenei mea, i whakahaere ngā, hoki i whakamahia te rangi maroke pure o te hauhā. I roto i te tauira tuatahi i whakaritea e te wera motuhake i te pēhanga tamau (Cp), te tuarua i te rōrahi tonu (CV) me tohu rite ine. Te mea faahiahia, i 0 ° uara Cp i 0,2402 cal / g · deg, me te CV o te hau taua - 0,1713 cal / g · deg. Ko te ōwehenga o enei uara homai te tawhā e whai ake thermodynamic, i te mea nui i roto i thermodynamics.

Hei whakatau i te aumou hau (R) tātai i te rerekētanga o te hau tikakatanga motuhake e ako i te pēhanga tamau (Cp) me i rōrahi tonu (CV). Ko te tikanga tinana o tenei uara ko ki te whakatau i te mahi roha, hei tauira, kotahi manokaramu o hau (hau) na roto i te whakanui ake i tona pāmahana i tetahi tohu (Kelvin).

I roto i ngā o mua ako matou nga āhuatanga ōkiko o te rangi maroke. I roto i te mahi tūturu, ko te mea e tika ana ki te tango i ki pūkete te ōrau o te mamaoa i roto i te reira (haumākū). wera motuhake he tona fakafalala me tauira huringa o te rangi kei roto i te nui tetahi o te wai (te korohū).

kua meinga rangi hou te kaupapa o te aronga i roto i te rangahau tinana, no te mea kua he pānga i runga i te maha o ngā tukanga tinana, me te ara matū te ihirangi mamaoa i roto i te reira. Ora kaiao he kahore okotahi. e kore e huringa haumākū pā anake nga tikanga microclimate o whare (tari, awheawhe, taiwhanga), engari he pānga i runga i te pai ngā kaimahi, te haumaru o te maha o ngā matū, me te ara te mahi o etahi whakaaro hoki kua.

he tauākī kore noa o meka, engari ano ki te rapu mō huarahi rerekē o awe nga āhuatanga o te rangi, ko te kaupapa o te rangahau. E ratou he faufaa nui i roto i mara ngā o mahi a te tangata, mai i te ahumahi matū, ki hanga o whare noho.
