Chii mashandisirwo emagetsi echoto chinonyungudutsa induction kunyungudutsa tani imwe yealuminium
Chii mashandisirwo emagetsi echoto chinonyungudutsa induction kunyungudutsa tani imwe yealuminium?
Iyo chaiyo yekupisa simba realuminium ndeye 0.88 × 103 J/(kg · ℃), iyo inonyungudika: 660.37 Kupisa kwekusanganiswa kwealuminium ndeye 3.98 × 105J/kg,
1 toni yealuminium inopisa kubva (25°C) kusvika 660°C, yobva yanyunguduka. Kune zvikamu zviviri zvekutora kupisa, chimwe chikamu kunyura nekupisa, uye chimwe chikamu kupisa kwechikamu chekuchinja.
Heating endothermic Q1=880×1000×(660-25)J=558800KJ
Phase shanduko kupisa Q2=1000×3.98×105=398000KJ
Kupisa kwese=558800+398000=956800KJ
Kupisa pakilowatt-awa ndeye 3600KJ, uye kupisa kwakanaka kunowanzo kutenderera 90%.
956800÷3600÷90%=295.31
Naizvozvo, zvinotora anenge 295 kWh kunyungudutsa 1 toni yealuminium, iyo inogona kunge isina kunyanya kunyatso. Ndinovimba ndinogona kukupa chinongedzo.
