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

Incazelo emfushane:

Imininingwane yomkhiqizo

Amathegi womkhiqizo

I-viscosity ye-Liquid ayisebenzisi kabanzi kuphela kubuchwepheshe bezobunjiniyela nezokukhiqiza, kepha futhi idlala indima ebalulekile kwi-biology nakwezokwelapha. Isibonelo, ukukala usayizi we-viscosity yegazi ngesinye sezimpawu ezibalulekile zempilo yegazi lomuntu. Uma kuqhathaniswa nendlela yebhola ewayo, lesi silingo sisebenzisa umthetho wokugeleza ketshezi olubonakalayo kushubhu le-capillary elime mpo. Inezinzuzo zesilinganiso sesampula esincane, amaphuzu wokushisa ahlukile nokunemba okuphezulu kwesilinganiso. Ifanele ikakhulukazi uketshezi olunama-viscosity coefficient amancane, njengamanzi, utshwala, amanzi nokunye Ukusetshenziswa kwalesi sitsha akugcini ngokwandisa ulwazi lwabafundi, kodwa futhi kukhulisa ikhono labo lokusebenza lokuhlola.

Ukuhlolwa

1. Qonda umthetho wePoiseuille

2. Funda ukuthi ungalinganisa kanjani ama-coefficients we-viscous and surface tension of liquid usebenzisa i-Ostwald viscometer
