I-LMEC-12 yokuMeta iViscosity yolwelo – Indlela yeCapillary eFakelweyo kuMfanekiso

I-LMEC-12 yokulinganisa i-Liquid Viscosity - Indlela yeCapillary

Inkcazelo emfutshane:

I-viscosity yolwelo ayisetyenziswanga kuphela kubunjineli kunye neteknoloji yokuvelisa, kodwa idlala indima ebalulekileyo kwibhayoloji nakwiyeza. Ngokomzekelo, ukulinganisa ubungakanani be-viscosity yegazi yenye yeempawu ezibalulekileyo zempilo yegazi lomntu. Xa kuthelekiswa nendlela yebhola ewayo, umthetho wokuhamba kwe-viscous fluid kwityhubhu ye-capillary ethe nkqo isetyenziswa kolu vavanyo. Ineenzuzo zesayizi encinci yesampula, amanqaku ahlukeneyo obushushu kunye nokuchaneka komlinganiselo ophezulu. Ngokukodwa ezilungele ulwelo viscosity ephantsi, ezifana namanzi, utywala, amanzi, njalo njalo Ukusetyenziswa kwesi sixhobo ukwandisa ulwazi lwabafundi kuphela, kodwa uhlakulele isakhono sabo sokulinga ukusebenza.
