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 Wm3, 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 WmK1. The two extreme faces are exposed to fluid with heat transfer coefficient 100 WmK and bulk temperature 30 C 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 T is measured to be 100 C, the right extreme face temperature T2 oC. 1S Left extreme face T1 = 100 C T2 1 m 1 m 1 m 100W/ .K 100W/ .K 30 C 30 C
