Pokey Kinematic. rehe inu

pokey Kinematic Ko te huru tinana faufaa o te hau katoa me pāpāho wai. he tino hira i roto i te whakatau i te rou o te totoka neke me te kawenga, wheako ai ratou tenei ahua. Ka rite ki matau ana koutou, i roto i to tatou ao i reira he tetahi kaupapa i roto i te rangi i te taiao rōwai ranei. I te wa ano i runga i te tinana neke tonu ki te pere kaha i te ritenga ki te ahunga o te kaupapa o te taonga ratou. Nä, ko te teitei te pokey kinematic o te reo, te atu te kawenga ite e te totoka. He aha te mea te āhua o te āhuatanga o wai , me hau?

pokey Kinematic, tautuhia rite te waku ā-he tika ki rāpoi kaihoko whakawhiti torohaki hāngai ki te aronga o te nekehanga o ona papa he tere rerekē. Hei tauira, i roto i wai ia o nga wae hanganga (muingota) Kei te karapotia i runga i taha katoa e ona hoa tata e kei āhua i te tawhiti rite ki to ratou diameter. pae ia rāpoi ngota huri noa te tūranga taurite pera-ka karanga, engari ka mau te ngātere i ona hoa tata, hanga ana e ia he peke koi ki te pokapū hou o te oscillation. He kōwae hanganga tuarua, taonga ia taua he wa ki te huri i te wahi o tona noho e pā ana ki ngā wā i te rau miriona, hanga i waenganui i te hūpeke i tetahi ki rau o nga mano o ngā rerekētanga. O te akoranga, te nui, ko te pāhekoheko rāpoi, te iti te nekeneke o ia kōwae hanganga me, no reira, atu taonga pokey kinematic.

Ki te mahi tetahi rāpoi ngota ope tamau waho i runga i te wahi o papa pātata, na te aronga o te matūriki te whakamamaetia displacement nui mo te kōwae i homai o te wā atu i roto i te huarahi i te ritenga. Na reira, kua tahuri te reira ki te kaupapa tika kaipaowe huru i te tetahi tere, i runga i nga ope mahi i runga i te reira rānei. Taua pokey tūturu, hei tauira, hinu nekeneke. He hoki nui te meka i piri ki te korakora i raro i whakaaro ope waho e mahi ana mahi i runga i rawe ki motu o nga paparanga roto i squeezes te rāpoi ngota. Taua te rongo te mutunga faarahi te auau o waiariki nekehanga matapōkere o nga matūriki, e kore nei e te huri ki te wā. I roto i te mau parau te tahi atu, te āhuatanga te irava inu kākahu ahakoa te rongo tonu ki ope waho i roto i ngā tohutohu rerekē no te mea kei te whärite ratou e te ā-ātete paparanga rauemi e ïa tautuhi ana te pokey kinematic.

Ka rite ki te pāmahana whakanuia ana te nekeneke o ngā rāpoi ngota tīmata ki te whakapiki ake i, e arata'i ki etahi hekenga o te parenga papa rauemi, rite tetahi taonga preheated tikanga atu pai mō te te kaupapa noa o te matūriki i te ahunga o te tōpana. Ka taea te whakaritea i tēnei ki te ara he tangata, ko te nui māmā ki te kotēhia i roto i te mano neke matapōkeretia atu whakaritea. He tohu nui o te pokey kinematic, whanganga i roto i Pascals Stokes-hēkona ranei i rongoā polymer. Ko te tika tenei ki te aroaro i roto i to ratou hanganga o nga mekameka rāpoi roa e hono etaeta. Otiia ki te whakanui ake auau pāmahana o ratou pokey heke tere. A, no te te te pēhi o te filamentary kirihou panaia tango ia rāpoi ngota bizarrely tu'ati te tūranga hou.

Ko o te tikanga o te 10 ^-5 Pa * s te pokey o te hau i te pāmahana o te 20 ° C, me te pēhanga kōhauhau o 101,3 Pa. Hei tauira, ka kia rite aua te pokey kinematic o rangi, haumāmā, hāora me te hauwai i raro i taua tikanga ki te 1.82 * 10 ^-5; 1.96 * 10 ^-5; 2.02 * 10 ^-5; 0.88 * 10 ^-5 Pa s. He haumāmā wai te tikanga roaa āhuatanga superfluid maere. Tenei āhuatanga, kitea e academician PL takoto Kapitsa i te meka e konganuku kaha i roto i taua āhua whakahiato kua tata kahore pokey. Hoki a ia, Ko tata kore tenei ahua.
