Uma ifinyelela ekuqondeni ukuziphatha koketshezi oluqinile nolwelwesi ngaphansi kokucindezeleka kokugunda, isithombe 2 sinikeza ukumelwa kwamehlo kwe-equation 3. I-viscosity, evame ukuvezwa kuma-centipoise, idlala umsebenzi obalulekile enkingeni yokunyakaza koketshezi. Ivame ukumelwa njenge-kinematic viscosity, eboniswa ngegama elithi volt, okuyisilinganiso se-viscosity kuya ku-density kanye ne-mugwump yamandla. Isibonelo, uwoyela osindayo ungadala i-kinematic viscosity ephezulu njenge-900 x 10-6m2 / umzuzwana, kuyilapho amanzi ebonisa inani eliphansi kakhulu le-berth elingu-1,14 x 10?m2 / umzuzwana ku-15 ° degrees centigrade. I-kinematic viscosity yolwelo iyehla ngokushisa okukhuphukayo, okwenza umoya ekushiseni kwegumbi i-engeli yehora i-kinematic viscosity cishe izikhathi ezingu-13 kunezamanzi.
Ukucindezeleka kobuso kuyisici esiyisisekelo esivumela isenzakalo esimangalisayo njengokumiswa kweconsi lamanzi ekuphambeni noma ukuntanta kweqabunga eli-acerate ebusweni boketshezi. Lesi sici sivela ekuvumelaneni phakathi kwe-molecule ebusweni boketshezi esebenzisana nolunye uketshezi noma igesi engaxubeki. Amandla okucindezeleka kobuso ngeyunithi ngayinye yobude bokulinganisa alinganiswa ku-manganese / imitha futhi mancane kakhulu, cishe ama-manganese angu-73 / imitha yamanzi ekushiseni kwegumbi. Nakuba ukucindezeleka kobuso ngokuvamile kungabalulekile ekusetshenzisweni kwe-hydraulic uma kuqhathaniswa namanye amandla, kuba yinto ebalulekile esimweni esinobuso obukhululekile kanye nobukhulu bomngcele omncane, njengakumamodeli e-hydraulic.
Umphumela owodwa okhanyayo wokucindezeleka kobuso yi-capillarity, lapho ithubhu elincane elivulekele emoyeni libonisa amandla amakhulu okucindezeleka kobuso. Lokhu kubonakala lapho ithubhu yengilazi icwiliswa emanzini, okwenza izinga lamanzi ngaphakathi kwethubhu likhuphuke futhi lakhe i-meniscus egobile. Lesi simo sibonisa ukuhlangana kokunamathelana phakathi kwamanzi nengilazi phezu kokuhambisana kwangaphakathi kwamanzi. Ukuqonda i-viscosity kanye nokucindezeleka kobuso koketshezi kubalulekile ekusetshenzisweni okuhlukahlukene kwesayensi nokusebenzayo, okukhanyisa ukuziphatha okuyinkimbinkimbi koketshezi ngaphansi kwezimo ezahlukene.
ukuqondaizindaba zebhizinisi:
Izindaba zebhizinisi zidlala indima ebalulekile ekugcineni umuntu enolwazi ngentuthuko yakamuva emhlabeni webhizinisi. Kungakhathaliseki ukuthi ukuhlanganiswa, ukuthengwa, ukuthambekela kwemakethe, noma umbiko wezezimali, ukubuyekezwa kwezindaba zebhizinisi kunganikeza ukungena okubalulekile kubatshalizimali, osomabhizinisi, kanye nochwepheshe ngokufanayo. Ngokuhlaziya izindaba zebhizinisi, umuntu angakwazi ukwenza izinqumo ezinolwazi oluhle, alindele ushintsho lwemakethe, futhi athole amathuba okukhula. Ngaphezu kwalokho, ukuqonda umthelela wesici sezomnotho, imithethonqubo yemboni, kanye nomcimbi womhlaba wonke ebhizinisini kuyadingeka ukuze kuhambele indawo yamandla okuziphatha emhlabeni webhizinisi. Sekukonke, ukuhlala unolwazi ngezindaba zebhizinisi kubalulekile ukuze uhlale uphambili endaweni yanamuhla yebhizinisi yokuncintisana.
