A 10-in.-thick concrete bridge deck is embedded with heating
cables, as shown in Figure P13–30. If the lower surface is at 0 F, the rate of
heat generation (assumed to be the same in each cable) is 100 Btu/(h-in.) and
the top surface of the concrete is at 35 F. The thermal conductivity of the
concrete is 0.500 Btu/(h-ft-F). What is the temperature distribution in the
slab? Use symmetry in your model.
