Ib qho kev qhib yog hom thermodynamic system qhov twg lub zog thiab teeb meem feem ntau pauv nrog nws ib puag ncig. Lub kaw lus kaw yog hom thermodynamic uas tsuas yog lub zog tuaj yeem hloov pauv nrog nws ib puag ncig tab sis tsis muaj teeb meem. Qhib tshuab tuaj yeem pauv qhov teeb meem nrog ib puag ncig.
Qhov twg hauv qab no yog qhov qhib qhov ntsuas kub?
Centrifugal twjyog qhov qhib qhov system.
Puas yog piv txwv ntawm qhib qhov system?
Ib qho piv txwv ntawm lub kaw lus qhib yog ib lub khob puv dej. Nyob rau hauv lub beaker uas muaj dej, cov dej molecules tuaj yeem khiav ntawm lub beaker thiab lub zog kub ntawm lub beaker thiab ib puag ncig tuaj yeem sib pauv nrog ib leeg.
Lub kaw lus qhib yog dab tsi?
Ib qho kev qhib yog lub kaw lus uas muaj cov ntaub ntawv ntws, lub zog, thiab / lossis teeb meem ntawm qhov system thiab nws ib puag ncig, thiab uas yoog rau kev sib pauv. Qhov no yog lub hauv paus ntsiab lus science txhais.
Yuav ua li cas qhib qhov system hauv mechanical engineering?
Ib qho qhib yog ib qho uas koj tuaj yeem ntxiv / tshem tawm qhov teeb meem(piv txwv li lub khob qhib uas peb tuaj yeem ntxiv dej). Thaum koj ntxiv qhov teeb meem- koj kuj xaus rau kev ntxiv cua sov (uas muaj nyob rau hauv qhov teeb meem). Lub kaw lus uas koj tsis tuaj yeem ntxiv qhov teeb meem yog hu ua kaw.
