Aone-dimensional plane wall of thickness 2l= 100 mm experiences uniform thermal energy generation of q˙= 1600 w/m3 and is convectively cooled at x= ±50 mm by an ambient fluid characterized by [infinity] t[infinity]= 20°c. if the steady-state temperature distribution within the wall is t(x)=a(l2-x2)+b where a= 10°c/m2 and b= 30°c, what is the thermal conductivity of the wall? what is the value of the convection heat transfer coefficient, h ?
