EXAMPLE 10.2 Consider the following body in which the inner face is at 200°C and the outer face is at 100°C. The body is very long so that heat transfer takes place in two dimensions only. The thermal conductivity of the body is 1.21 W/m-K. The dimensions of the 1 = 4y=²2/₁ body are shown in Fig. 10.4. Take Ar = Ay m.
