Cov txheej txheem tiv thaiv hluav taws ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov qauv los ntawm kev puas tsuaj los ntawm hluav taws. Ib qho tseem ceeb uas cuam tshuam rau kev ua haujlwm ntawm cov txheej txheem no yog viscosity. Viscosity txhais tau tias yog qhov ntsuas ntawm cov kua dej tsis kam rau kev ntws.

Hauv cov ntsiab lus ntawm cov txheej txheem tiv thaiv hluav taws, kev nkag siab txog qhov cuam tshuam ntawm viscosity yog qhov tseem ceeb rau kev ua kom muaj kev tiv thaiv hluav taws zoo.

Ua ntej, qhov viscosity cuam tshuam rau qhov yooj yim ntawm kev siv cov txheej tiv thaiv hluav taws. Cov txheej uas muaj viscosity siab dua feem ntau yuav tuab dua thiab nyuaj rau nthuav dav sib npaug. Qhov no tuaj yeem ua rau cov tuab tsis sib npaug thoob plaws qhov chaw coated, ua rau muaj qhov sib txawv thiab qhov tsis muaj zog hauv kev tiv thaiv hluav taws.

Ntawm qhov tod tes, cov txheej txheem uas muaj viscosity qis dua yooj yim dua rau kev thov thiab tuaj yeem ua tiav qhov tuab sib xws, txhim kho qhov kev tiv thaiv hluav taws tag nrho ntawm thaj chaw tiv thaiv.

Tsis tas li ntawd xwb, qhov viscosity cuam tshuam rau lub sijhawm ziab thiab zaj duab xis ntawm cov txheej tiv taus hluav taws. Cov txheej uas muaj viscosity siab dua feem ntau siv sijhawm ntev dua kom qhuav thiab tsim cov zaj duab xis khov kho. Thaum lub sijhawm ziab no, cov txheej yuav raug puas tsuaj, xws li hmoov av lossis cov khib nyiab lo rau ntawm qhov chaw ntub dej.

Qhov sib txawv, cov txheej txheej uas muaj viscosity qis dua yuav qhuav sai dua thiab tsim cov zaj duab xis khov kho uas muaj feem tsawg kawg nkaus ntawm kev ua qias tuaj. Qhov no ua kom muaj kev ruaj khov zoo dua thiab kev tiv thaiv hluav taws mus sij hawm ntev.

Tsis tas li ntawd xwb, qhov viscosity cuam tshuam rau lub peev xwm ntawm cov txheej tiv taus hluav taws kom nkag mus thiab lo rau ntau qhov chaw. Cov txheej txheem uas muaj viscosity siab dua yuav nyuaj rau nkag mus rau hauv cov kab nrib pleb lossis cov chaw tsis sib luag, ua rau tsis txaus npog thiab txo qis kev tiv thaiv hluav taws.

Qhov sib piv, cov txheej txheem viscosity qis dua tuaj yeem nkag mus tau yooj yim thiab lo rau ntawm qhov chaw, ua kom muaj kev npog tag nrho thiab ua kom muaj kev tiv thaiv hluav taws ntau tshaj plaws.

Thaum kawg, viscosity cuam tshuam rau tag nrho kev ua tau zoo thiab kev ua haujlwm ntawm cov txheej tiv thaiv hluav taws. Cov txheej nrog qib viscosity zoo tshaj plaws tuaj yeem muab kev rwb thaiv cua sov zoo dua, qeeb qeeb kev sib kis hluav taws, thiab tiv thaiv kev tso tawm cov pa phem. Ntawm qhov tod tes, cov txheej nrog viscosity siab dhau heev tuaj yeem cuam tshuam lub peev xwm ntawm cov txheej kom teb tau zoo rau cua sov, ua rau nws cov peev xwm tiv thaiv hluav taws puas tsuaj.

Xaus lus, viscosity ua lub luag haujlwm tseem ceeb hauv kev ua tau zoo ntawm cov txheej tiv thaiv hluav taws. Nws cuam tshuam rau qhov yooj yim ntawm kev siv, lub sijhawm qhuav, kev tsim zaj duab xis, kev nkag mus, thiab kev ua haujlwm zoo ntawm cov txheej. Kev nkag siab thiab kev tswj hwm qhov viscosity ntawm cov txheej tiv thaiv hluav taws yog qhov tseem ceeb rau kev ua kom ntseeg tau tias cov qauv tau tiv thaiv txaus los ntawm kev phom sij hluav taws.
