Cov kinematic viscosity [m2/s] yog qhov piv ntawm qhov dynamic viscosity [Pa. s = 1 kg/m·s] thiab qhov ntom ntawm cov kua [kg/m3]. Unit SI kinematic viscosity yog m2/s. Dej ntawm 20 ° C muaj a kinematic viscosity ib kb1cst.
Raws li, kinematic thiab dynamic viscosity yog dab tsi?
Qhov thib ob feem ntau hom ntawm viscosity yog dynamic thiab kinematic . Dynamic viscosity (tseem hu ua viscosity kiag li ) yog qhov ntsuas ntawm cov kua dej sab hauv tsis kam ntws thaum kinematic viscosity hais txog qhov piv ntawm dynamic viscosity kom ceev.
Ib yam li ntawd, koj yuav suav li cas kinematic viscosity? Kinematic viscosity tuaj yeem tau los ntawm kev faib cov dynamic viscosity ntawm cov kua los ntawm nws qhov ntom. Lub Stokes (St) yog cgs lub cev chav tsev rau kinematic viscosity , muaj npe tom qab George Gabriel Stokes, qhov twg 1 St = 10-4 m2/s. Nws kuj tau qhia nyob rau hauv cov nqe lus ntawm centistokes (cSt los yog ctsk).
Yog li ntawd, kinematic viscosity txhais li cas?
Kinematic viscosity yog ib qho kev ntsuas ntawm cov kua dej sab hauv tsis kam ntws hauv qab gravitational rog. viscosity tuaj yeem ntsuas thiab tshaj tawm raws li dynamic (tsis meej) viscosity los yog li kinematic viscosity.
Dab tsi yog qhov tseem ceeb ntawm kinematic viscosity?
Lwm txoj hauv kev yog ntsuas qhov kev tawm tsam ntawm cov kua hauv qab qhov hnyav ntawm lub ntiajteb txawj nqus. Qhov tshwm sim yog kinematic viscosity . Muab lwm txoj kev, kinematic viscosity yog qhov ntsuas ntawm cov kua dej uas muaj nyob hauv qhov tsis kam ntws thaum tsis muaj zog sab nraud, tshwj tsis yog lub ntiajteb txawj nqus, ua rau nws.

Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
