hey i really need help with solving this question.
1. Homework Statement
the problem is in one dimention x ( 2 plates with diffrent K joined together)
for x=0 T=500 ( constat temp)
0<x<L - electric wire is generating heat that maintane the constant temp in x=0 ,it has K=40W/mK.
L<x<2L - there is rubber preventing electriciution and heat loss Ki= 0.2 W/Km , where T(2L)=300K(constant).
how do i find the tempreture distribiotion in the 0<x<2L? (q* gen should be unknown but expressed in the finle answer)
please help :(
foriers' law of conduction & Qin-Qout+Qgen=Qacc
i can find the distribution using the heat balance integral.. but I am not sure about the temperature at x=L..
