LMEC-12 Ke ana ʻana i ka viscosity wai - Ka hana Capillary
ʻAʻole hoʻohana wale ʻia ka viscosity wai i ka ʻenehana a me nā ʻenehana hana, akā he mea nui nō hoʻi i ka biology a me ka lāʻau. ʻO kahi laʻana, ke ana ʻana i ka nui o ka viscosity o ke koko kekahi o nā hōʻailona koʻikoʻi o ke olakino koko kanaka. Hoʻohālikelike ʻia me ke ʻano o ke kinipōpō hāʻule, e hoʻohana ana kēia hoʻokolohua i ke kānāwai kahe o ka wai viscous i ka paipu capillary kū aʻe. Loaʻa iā ia nā pōmaikaʻi o ka nui o nā hāpana, nā helu mahana like ʻole a me ke ana kiʻekiʻe o ke ana. Kūpono loa ia no nā wai me ka coefficient viscosity liʻiliʻi, e like me ka wai, ka wai ʻona, ka wai a pēlā aku ʻO ka noi ʻana o kēia mea kani ʻaʻole ia e hoʻonui wale i ka ʻike o nā haumāna, akā mahi pū nō hoʻi i kā lākou hana hoʻokolohua hiki.
Nā hoʻokolohua
1. Hoʻomaopopo i ke kānāwai Poiseuille
2. E aʻo pehea e ana ai i nā coefficients viscous a me ka pae o ka wai e hoʻohana ana iā Ostwald viscometer
