2. A rectangular block has thickness B in the x-direction. The side at x =0 is held at temperature T, while the side at x =B is held at T2. The other four sides are well insulated. Heat is generated in the block at a uniform rate per unit volume of T. (a) Use the conduction equation to derive an expression for the steady-state temperature profile, T(x). Assume constant thermal conductivity. (b) Use the result of part (a) to calculate the maximum temperature in the block for the following values of the parameters: Ti=120 C -0.2 W/(mK) B=1.0 m T2=0 T=100 W/m
