A flat wall with thickness 2L and thermal conductivity k experiences a uniform generation of heat. Considering the stationary state, determine the expression for the temperature variation inside the wall if:
a)T1>T2
b) Is the temperature distribution T(x) in part a) symmetric about the central line x=0? Why?
c) T1=T2
d) Using the previous result, show that in the absence of internal heat generation there is no temperature variation inside the wall when T1=T2
