Unit system: Centimeter-gram-thib ob system

Ib yam li ib tug yuav nug, dab tsi yog chav tsev rau viscosity?

Txawm nyob rau hauv kev sib raug zoo nrog high- viscosity dej, qhov no chav tsev feem ntau yog ntsib raws li centipoise (cP), uas yog 0.01 poise. Muaj ntau cov kua dej txhua hnub viscosities nruab nrab ntawm 0.5 thiab 1000 cP (saib cov lus). Pascal-thib ob (symbol: Pa. s)This is the SI chav tsev ntawm viscosity , sib npaug tonewton-thib ob ib square meter (N.

Kuj Paub, poise physics yog dab tsi? Cov poise yog ib chav ntsuas ntawm dynamicviscosity A poise (P) yog qhov ntsuas tsis yog-SI (tsis yog-SystemInternational) ntsuas ntawm cov viscosity dynamic nyob rau hauv lub cmimeter gram thib ob (CGS) system ntawm units. Nws muaj npe tom qab tus kws kho mob Fab Kis thiab tus kws kho mob lub cev Jean Louis Marie Poiseuille (22 Plaub Hlis 1797 - 26 Kaum Ob Hlis 1869).

Dhau li ntawm no, poise xam li cas?

Stokes = A x Poise / (Fluid Density) qhov twg A = 1000, yog cov kua ntom ntom ntsuas hauv kg ib cubic meter. Thatis, ntawm tus qauv siab thiab 15 C kub, qhov dynamic viscosity ntawm huab cua yog kwv yees li 0.000173 poise , thiab thekinematic viscosity ntawm huab cua yog kwv yees li 0.141 stokes.

Stoke unit yog dab tsi?

Cov stoke yog a chav tsev Kev ntsuas ntawm kinematic viscosity A stoke (St) yog centimeter-gram-thib ob (CGS) chav tsev ntawm kinematic viscosity. Cov chav tsev yog lub npe hu ua British physicist thiab mathematician Sir George Gabriel Stokes (13 Aug 1819 – 1 Feb 1903)
