Consider the conducting rod of Example 1.3 under steady-state conditions. As suggested in Comment 3, the temperature of the rod may be controlled by varying the speed of air flow over the rod, which, in turn, alters the convection heat transfer coefficient. To consider the effect of the convection coefficient, generate plots of T versus I for values of h = 50, 100, and 250 W/m 2 0 K. Would variations in the surface emissivity have a significant effect on the rod temperature?
