I-LMEC-12 Ukulinganisa Ulwelo Oluxineneyo – Indlela yeCapillary

Inkcazo emfutshane:

I-liquid viscosity ayisetyenziswa kakhulu kubunjineli nakwiteknoloji yemveliso kuphela, kodwa ikwadlala indima ebalulekileyo kwibhayoloji nakwizonyango. Umzekelo, ukulinganisa ubungakanani be-viscosity yegazi yenye yeempawu ezibalulekileyo zempilo yegazi lomntu. Xa kuthelekiswa nendlela yebhola ewelayo, umthetho wokuhamba kolwelo oluxineneyo kwityhubhu ye-capillary ethe nkqo usetyenziswa kolu vavanyo. Inezibonelelo zobukhulu obuncinci besampulu, amaqondo obushushu ahlukeneyo kunye nokuchaneka okuphezulu kokulinganisa. Ifanelekile ngokukodwa kwi-viscosity ephantsi, njengamanzi, utywala, amanzi, njl. Ukusetyenziswa kwesi sixhobo akugcini nje ngokwandisa ulwazi lwabafundi, kodwa kukwakhulisa nokukwazi kwabo ukusebenza kovavanyo.
