I-LMEC-12 Yokulinganisa Ukuqina Koketshezi – Indlela Ye-Capillary Isithombe Esifakiwe

Indlela Yokulinganisa Ukuqina Koketshezi lwe-LMEC-12 - Indlela Ye-Capillary

Incazelo emfushane:

I-liquid viscosity ayisetshenziswa kabanzi kuphela kwezobunjiniyela kanye nobuchwepheshe bokukhiqiza, kodwa futhi idlala indima ebalulekile ku-biology kanye nezokwelapha. Isibonelo, ukukala usayizi we-viscosity yegazi kungenye yezimpawu ezibalulekile zempilo yegazi lomuntu. Uma kuqhathaniswa nendlela yebhola eliwela phansi, umthetho wokugeleza koketshezi olunamathelayo ku-vertical capillary tube usetshenziswa kulolu vivinyo. Inezinzuzo zobukhulu obuncane besampula, amaphuzu okushisa ahlukene kanye nokunemba okuphezulu kokulinganisa. Ifaneleka kakhulu uketshezi olunamathelayo oluphansi, njengamanzi, utshwala, amanzi, njll. Ukusetshenziswa kwalesi thuluzi akugcini nje ngokwandisa ulwazi lwabafundi, kodwa futhi kuthuthukisa ikhono labo lokusebenza lokuhlola.

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Ukuhlolwa

1. Qonda umthetho we-poiseuille

2. Funda ukuthi ungalinganisa kanjani ama-coefficients aqinile kanye nokuqina kobuso boketshezi usebenzisa i-ostwald viscometer
