Lub zog noj ntawm qhov cub induction melting rau 1 tuj ntawm txhuas yog dab tsi?

Qhov tshwj xeeb kub muaj peev xwm ntawm txhuas yog 0.88 × 103 J / (kg· ℃), lub melting point: 660.37 Lub tshav kub ntawm fusion ntawm txhuas yog 3.98 × 105J / kg,

1 tuj ntawm txhuas yog rhuab los ntawm (25 ° C) mus rau 660 ° C, thiab ces melted. Muaj ob feem ntawm kev nqus cua sov, ib feem yog qhov nqus cua sov los ntawm cua sov, thiab lwm qhov yog cua sov ntawm theem hloov.

Heating endothermic Q1=880×1000×(660-25)J=558800KJ

Theem hloov kub Q2 = 1000 × 3.98 × 105 = 398000KJ

Tag nrho cov cua sov = 558800 + 398000 = 956800KJ

Thaum tshav kub kub ib kilowatt-teev yog 3600KJ, thiab cov cua kub efficiency feem ntau yog nyob ib ncig ntawm 90%.

956800÷3600÷90% = 295.31

Yog li ntawd, nws yuav siv li 295 kWh kom yaj 1 tuj ntawm txhuas, uas tej zaum yuav tsis yog qhov tseeb. Kuv vam tias kuv tuaj yeem muab rau koj siv.
