viscosity kev ntsuas yog siv nyob rau hauv kev lag luam khoom noj kom maximize ntau lawm efficiency thiab nqi efficiency. Nws cuam tshuam rau tus nqi ntawm cov khoom mus los ntawm cov yeeb nkab, nws yuav siv sij hawm ntev npaum li cas los teeb lossis qhuav, thiab lub sij hawm nws yuav siv sij hawm los faib cov kua rau hauv ntim.
Ntxiv rau qhov no, dab tsi yog siv cov viscosity?
Hauv lubrication, roj viscosity yog tus yam ntxwv tseem ceeb tshaj plaws. Nws yuav tsum yog. Qhov tseeb viscosity muab koj lub peev xwm los lubricate, uas txhais tau hais tias muaj peev xwm tiv thaiv kev hnav (los ntawm kev sib cais ntawm qhov chaw) thiab txo kev sib txhuam.
Tom qab ntawd, lo lus nug yog, piv txwv li viscosity yog dab tsi? Cov viscosity Cov kua dej yog ib qho kev ntsuas ntawm nws qhov tsis kam mus deformation ntawm tus nqi muab. Rau cov kua, nws sib raug rau lub tswv yim tsis raws cai ntawm "thickness": rau piv txwv , syrup muaj ntau dua viscosity dua dej. Cov kua dej nrog lub siab viscosity , xws li suab, tej zaum yuav zoo li yog ib qho khoom.
Hauv qhov no, vim li cas viscosity tseem ceeb?
Cov Qhov tseem ceeb ib Oil viscosity . viscosity cuam tshuam rau kev tsim hluav taws xob hauv cov kabmob, lub tog raj kheej thiab cov iav teeb muaj feem xyuam rau cov roj hauv kev sib txhuam. viscosity yog ib qho kev ntsuas ntawm cov roj tsis kam ntws. Nws txo qis (thins) nrog nce kub thiab nce (los yog thickens) nrog txo qhov kub.
Dab tsi yog hu ua viscosity?
viscosity , tsis kam ntawm cov kua (kua lossis roj) rau kev hloov pauv hauv cov duab, lossis kev txav ntawm cov neeg nyob sib ze ntawm ib leeg. viscosity qhia txog kev tawm tsam kom ntws. Lub reciprocal ntawm lub viscosity yog hu ua fluidity, ib qho kev ntsuas ntawm qhov yooj yim ntawm ntws. Molasses, piv txwv li, muaj ntau dua viscosity dua dej.

Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?
Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Lub viscosity ntawm cinder cone volcano yog dab tsi?
Spheroidal thiab ntxaiv-zoo li lub foob pob muaj ntau ntawm cinder cones. Tsis zoo li cov hluav taws kub hnyiab uas tsim cov stratovolcanoes loj, cinder cones tsim thaum qis-viscosity lava nrog ntau cov roj erupts, feem ntau ua kua dej. Lava tej zaum yuav spewed pua pua ntawm cov huab cua
Dab tsi cuam tshuam rau viscosity ntawm magma?
Viscosity ntawm Magmas Viscosity yog qhov tsis kam ntws (tawm ntawm fluidity). Viscosity nyob ntawm feem ntau ntawm cov magma, thiab kub. Siab dua SiO2 (silica) cov ntsiab lus magmas muaj viscosity ntau dua li SiO2 cov ntsiab lus magmas (viscosity nce nrog nce SiO2 concentration hauv magma)
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
