Heat is conducted along a metal rod positioned between two fixed temperature walls. Aside from conduction, heat is transferred between the rod and the surrounding air by convection. Based on a heat balance, the distribution of temperature along the rod is described by the following second-order differential equation dT +h'(T T) 0 = | where T = temperature (K), h' = a bulk heat transfer coefficient reflecting the relative importance of convection to conduction (m-2), x = distance along the rod (m), and Too = temperature of the surrounding fluid (K). (a) Convert this differential equation to an equivalent system of simultaneous algebraic equations using a centered difference approximation for the second derivative. (b) Develop a function to solve these equations from x = 0 to L and return the resulting distances and temperatures. The first line of your function should be function [x, y] = YourLastName_rod(hp, Tinf, TO, TL, L, dx) (c) Develop a script that invokes this function and then plots the results. (d) Test your script for the following parameters: h' = 0.0425 m-2, L = 12 m, T0 220 K, T(0) = 320 K, T(L) = 450 K, and Ax = 0.5 m.
