I-LMEC-12 Measuring Liquid Viscosity – Indlela Ye-Capillary Isithombe Esifakiwe

I-LMEC-12 yokulinganisa i-Liquid Viscosity - Indlela ye-Capillary

Incazelo emfushane:

I-liquid viscosity ayisetshenziswa kabanzi kwezobunjiniyela kanye nobuchwepheshe bokukhiqiza, kodwa futhi idlala indima ebalulekile kubhayoloji nemithi.Isibonelo, ukulinganisa ubukhulu be-viscosity yegazi kungenye yezimpawu ezibalulekile zempilo yegazi lomuntu.Uma kuqhathaniswa nendlela yebhola eliwayo, umthetho wokugeleza koketshezi lwe-viscous kushubhu le-capillary mpo usetshenziswa kulokhu kuhlolwa.Inezinzuzo zosayizi omncane wesampula, amaphuzu okushisa ahlukene kanye nokunemba okuphezulu kokulinganisa.Ikakhulukazi efanelekayo ongaphakeme viscosity liquid, njengamanzi, utshwala, amanzi, njll Ukusetshenziswa kwaleli thuluzi hhayi kuphela andisa ulwazi abafundi, kodwa futhi kuhlakulele operation ikhono labo zokuhlola.

Thumela i-imeyili kithi

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izivivinyo

1. Qonda umthetho we-poiseuille

2. Funda ukuthi ungakala kanjani i-viscous kanye ne-surface tension coefficients yoketshezi usebenzisa i-ostwald viscometer
