LMEC-12 Kev Ntsuas Cov Kua Ua Ntsuas - Cov Qauv Capillary

Cov lus piav qhia luv luv:

Khoom Nthuav dav

Cov khoom lag luam

Cov kua viscosity tsis yog siv dav hauv kev siv tshuab thiab kev tsim khoom, tab sis tseem ua lub luag haujlwm tseem ceeb hauv biology thiab tshuaj. Piv txwv, ntsuas qhov loj ntawm cov ntshav viscosity yog ib qho ntawm cov cim tseem ceeb ntawm tib neeg cov ntshav noj qab haus huv. Piv nrog rau pob poob qis, qhov kev sim no siv cov kev cai lij choj ntws ntawm cov dej khov ua kua rau hauv cov hlab ntsws ntsug. Nws muaj qhov zoo ntawm cov qauv tsawg dua, cov ntsiab lus kub sib txawv thiab ntsuas qhov ntsuas qhov tseeb. Nws yog qhov tshwj xeeb tshaj yog rau cov kua uas muaj cov viscosity me me, xws li dej, dej cawv, dej thiab lwm yam Daim ntawv thov ntawm qhov ntsuas tsis tsuas nthuav cov tub ntxhais kawm kev paub, tab sis kuj cog lawv cov peev xwm ua haujlwm hauv kev sim.

Kev sim

1. Nkag siab Poiseuille txoj cai

2. Kawm paub ntsuas cov khov khov thiab sab hauv siab qhov sib tshooj ntawm cov kua uas siv Ostwald viscometer
