Q. Three slabs are joined together as shown in the figure. There is no thermal contact resistance at the interfaces. The center slab experiences a non-uniform internal heat generation with an average value equal to 10000 Wm−3, while the left and right slabs have no internal heat generation. All slabs have thickness equal to 1 m and thermal conductivity of each slab is equal to 5 Wm−1K−1. The two extreme faces are exposed to fluid with heat transfer coefficient 100 Wm−2 K−1 and bulk temperature 30 ºC as shown. The heat transfer in the slabs is assumed to be one dimensional and steady, and all properties are constant. If the left extreme face temperature T1 is measured to be 100 ºC, the right extreme face temperature T2 is ºC.
