Yuav kom ua tiav 100% kev ua tau zoo (η=1), Q2 yuav tsum sib npaug rau 0 uas txhais tau hais tias tag nrho cov tshav kub hauv qhov chaw hloov mus ua haujlwm. Qhov kub ntawm lub dab dej txhais tau hais tias qhov ntsuas kub tsis zoo ntawm qhov ntsuas qhov tseeb ntawm qhov ntsuas kub siab tshaj qhov sib sau.
Canot lub cav cua sov puas tuaj yeem ua tau 100% kev ua haujlwm?
Nws tsis yooj yim rau cov tshuab cua sov kom ua tiav 100%thermal efficiency raws li Txoj Cai Thib Ob ntawm thermodynamics. Qhov no yog tsis yooj yim sua vim hais tias qee qhov hluav taws kub khib nyiab ib txwm ua nyob rau hauv lub cav cua sov, qhia hauv daim duab 1 los ntawm lub sij hawm.
Cannot efficiency yog 100 feem pua?
Carnot's interesting result implies that 100% efficiency will be tsuas yog Tc=0 K-uas yog, tsuas yog txias xwb reservoir nyob ntawm qhov xoom, ib qho kev ua tau zoo thiab theoretical impossibility. … PV daim duab rau lub voj voog Carnot, ua haujlwm tsuas yog thim rov qab isothermal thiab adiabatic txheej txheem.
Vim li cas kev ua haujlwm ntawm Carnot cav yog siab tshaj?
Lub Carnot Efficiency yog qhov theoretical siab tshaj qhov ua tau zoo ib qho tuaj yeem tau txais thaum lub tshuab cua sov ua haujlwm ntawm ob qhov kub thiab txias : Qhov kub ntawm qhov kub ntawm qhov dej txias ua haujlwm (T Hot). Qhov kub ntawm qhov chaw cia khoom qis qis ua haujlwm (TCold).
Kev ua haujlwm ntawm lub cav Carnot yog dab tsi?
Kev ua haujlwm ntawm carnot lub cav yog50%.
