Viscosity feem ntau yog ywj siab ntawm siab, tab sis cov kua dej nyob rau hauv siab heev feem ntau muaj kev nce hauv viscosity. Txij li thaum cov kua dej ib txwm tsis muaj kev sib txuas, qhov nce hauv siab tsis tshua coj cov molecules los ze zog ua ke.
Lub siab cuam tshuam li cas viscosity?
Nias muaj qhov cuam tshuam rau ob qho tib si, viscosity ntawm cov kua li zoo li gases. Ntawm kev nce siab viscosity ntawm cov kua molecules nce vim qhov nce hauv qhov tsis kam mus rau cov dej ntws. Ntawm kev nce siab, cov viscosity ntawm cov roj molecules txo qis vim qhov nce hauv ci ntawm molecules.
Vim li cas viscosity tsis nyob ntawm qhov siab?
Thaum cov roj gases vim li cas viscosity yog molecular collision, yog li thaum peb nce qhov kub ntawm cov roj sib tsoo ntawm cov molecules nce thiab li no cov viscosity nce. Nyob rau hauv ib qho zoo sib xws, siab kuj cuam tshuam rau viscosity coefficient.
Yuav ua li cas rau viscosity thaum siab nce?
Thaum lub siab siab tshaj qhov npuas taw tes, viscosity nce nrog nce siab vim compression ntawm cov kua. Yam tsawg kawg nkaus viscosity yuav tshwm sim ntawm lub siab saturation. Kev hloov pauv ntawm cov roj viscosity nrog lub siab yog qhia hauv daim duab 5.15.
Ntawm dab tsi yog qhov viscosity nyob ntawm?
Viscosity is resistance to flow. Rau cov kua dej, feem ntau qhov loj dua qhov sib txawv ntawm cov rog (IMF) qhov siab dua qhov viscosity. Lwm yam uas cuam tshuam rau viscosity yog qhov kub thiab txias thiab cov duab ntawm cov molecule.
