I-LMEC-12 yokulinganisa i-Viscosity ye-Liquid-yeCapillary Method
I-viscosity yolwelo ayisetyenziswanga kuphela kubunjineli nakwitekhnoloji yokuvelisa, kodwa ikwadlala indima ebalulekileyo kwibhayoloji nakumayeza. Umzekelo, ukulinganisa ubungakanani be-viscosity yegazi yenye yeempawu ezibalulekileyo zempilo yegazi lomntu. Xa kuthelekiswa nendlela yebhola ewayo, eli linge lisebenzisa ukuhamba komthetho we-viscous fluid kwityhubhu ye-capillary ethe nkqo. Inezinto eziluncedo zobungakanani besampulu encinci, amanqaku obushushu ahlukeneyo kunye nokuchaneka kwemilinganiselo ephezulu. Ilungele ngokukodwa ulwelo olunomlinganiso omncinci we-viscosity, njengamanzi, utywala, amanzi njalo njalo Ukusetyenziswa kwesi sixhobo akupheleli nje ekwandiseni ulwazi lwabafundi, kodwa kukwakhulisa nokusebenza kwabo kokulinga.
Uvavanyo
1. Qonda umthetho wePoiseuille
2. Funda indlela yokulinganisa ii-viscous kunye ne-tension coefficients zolwelo usebenzisa i-Ostwald viscometer
