LMEC-12 Fuaina o le Liquid Viscosity - Capillary Metotia
E le gata ina lautele le faʻaogaina o le viscosity i le inisinia ma le gaosiga o tekonolosi, ae o loʻo taua ai foʻi le taua i le paiolo ma vailaʻau. Mo se faʻataʻitaʻiga, o le fuaina o le lapoʻa o le toto viscosity o se tasi o faʻailoga taua o le soifua maloloina o le toto o le tagata. Faʻatusatusa i le pa'ū polo auala, lenei faʻataʻitaʻiga faʻaaogaina le tafe tulafono o viscous suavai i le tūsaʻo capillary paipa. E i ai le lelei o le laʻititi faʻataʻitaʻiga aofaʻiga, eseese vevela togi ma maualuga fua fua. E sili ona talafeagai mo suavai ma laʻititi viscosity coefficient, pei o le vai, 'ava malosi, vai ma isi mea O le faʻaogaina o lenei mea faʻatino e le gata faʻalauteleina ai le malamalama o tamaiti aʻoga, ae faʻapupuina foʻi a latou gaioiga faʻataʻitaʻi agavaʻa.
Faʻataʻitaʻiga
1. Malamalama i le tulafono Poiseuille
2. Aʻoaʻo pe faʻafefea ona fua le viscous ma luga o feteʻenaʻiga coefficients o suavai faʻaaogaina Ostwald viscometer
