LMEC-12 Ho Lekanya Phallo ea Metsi - Mokhoa oa Capillary
Metsi a viscosity ha a sebelisoe hohle ho boenjiniere le theknoloji ea tlhahiso, empa hape a bapala karolo ea bohlokoa ho baeloji le bongaka. Mohlala, ho lekanya boholo ba viscosity ea mali ke e 'ngoe ea matšoao a bohlokoa a bophelo bo botle ba mali a motho. Ha e bapisoa le mokhoa oa bolo o oang, teko ena e sebelisa molao oa phallo ea mokelikeli oa viscous ka har'a tube ea capillary e emeng. E na le melemo ea bongata bo fokolang ba sampole, lintlha tse fapaneng tsa mocheso le ho nepahala ho phahameng. E loketse haholo-holo maro a nang le coefficient e nyane ea viscosity, joalo ka metsi, joala, metsi joalo-joalo Ts'ebeliso ea sesebelisoa sena ha e holise tsebo ea baithuti feela, empa e boetse e hlaolela bokhoni ba bona ba ts'ebetso ea liteko.
