Isingeniso
Emkhakheni wokucutshungulwa kwezinto kanye nobuchwepheshe bokuhlukanisa, ukuhlukaniswa okusekelwe ekuminyana kugqama njengendlela eyisisekelo yokuhlunga izingxube ezihlukene. Le nqubo incike ekuhlukeni kokuminyana kwezinto ezibonakalayo ukuze kuzuzwe ukuhlukaniswa okuphumelelayo. Eqhulwini lobu buchwepheshe Izisetshenziswa Zokuhlunga Amandla Adonsela phansi , ezisebenzisa amandla adonsela phansi ukuze kube lula inqubo yokuhlukanisa. Ukuqonda ukuthi kungani ukuhlunga amandla adonsela phansi kuphumelela ekuhlukaniseni okusekelwe ekuminyana kudinga ukucwiliswa okujulile ezimisweni zokugxilisa amandla adonsela phansi, idizayini yesisetshenziswa, kanye nokusetshenziswa kwayo kuzo zonke izimboni ezihlukahlukene.
Izimiso Zokuhlunga amandla adonsela phansi
Ukuhlelwa kwamandla adonsela phansi kusekelwe esimisweni sokuthi izinhlayiya zokuminyana okuhlukene zizosabela ngendlela ehlukile lapho zingaphansi kwamandla adonsela phansi. Le mpendulo ithonywa izici ezifana nosayizi wezinhlayiyana, umumo, kanye nendawo lapho ukuhlukana kwenzeka khona—kungaba umoya, amanzi, noma indawo eminyene. Umthetho oyisisekelo olawula le nqubo uMthetho kaStokes, ochaza isivinini sezinhlayiya oketshezini. Izinhlayiya ezisindayo ezinokuminyana okuphezulu zihlala ngokushesha kunezilula, okuvumela ukuhlukana ngokusekelwe kumazinga okukhokha.
Umthetho we-Stokes' kanye nokulungiswa kwezinhlayiya
Umthetho kaStokes uhlinzeka ngohlaka lwethiyori lokuqonda ukuhla kwezinhlayiyana endaweni ewuketshezi. Umthetho uthi isivinini sokuhlala sezinhlayiya eziyindilinga silingana ngokuqondile nesikwele sendawo engaba phakathi kwawo kanye nomehluko wokuminyana phakathi kwezinhlayiya noketshezi, futhi ngokuphambene ngokulinganayo ne-viscosity yoketshezi. Ngokwezibalo, imelelwa kanje:
\[ v = \frac{2}{9} \frac{(r^2)(\rho_p - \rho_f)g}{\mu} \]
Lapho \( v \) ijubane lokumisa, \( r \) iyindawo eyizinhlayiyana, \( \ rho_p \) ukuminyana kwezinhlayiyana, \( \ rho_f \) ukuminyana koketshezi, \( g \) ukusheshisa ngenxa yamandla adonsela phansi, futhi \( \ i-vi \ musco).
