[問題] 一題熱傳導問題
A stainless steel saucepan,with a base that is made of 0.35cm thick steel
[kss=46.0 W/(m.K)] fused to a 0.15 cm thickness of copper [kcu=401.0W/(m.K],
sits on a ceramic heating element at 104.0°C.The diameter of the pan is
18.0cm,
and it contains boiling water at 100.0°C.
(a)If the copper-clad bottom is touching the heat source,what is the temperat
ure
at the copper-steel interface?
(b)At what rate will the water evaporate from the pan?
抱歉大家,那個時候沒有注意版規
這題我想問的是給熱傳導係數之後
一個穩定的熱源104°C
我該怎麼
(a)求得兩個材料間的溫度
(b)他問了蒸發的速率,該怎麼由已提供資訊去求出水蒸發的速率呢
抱歉這題比較不知道怎麼著手,希望大家能幫忙,麻煩了
