Question:
A long, 1-cm-diameter electric cable is embedded in a concrete wall (k = 0.13 W/m K) that is 1 m × 1 m, as shown in the sketch. If the lower surface is insulated, the surface of the cable is 100ºC, and the exposed surface of the concrete is 25ºC, estimate the rate of energy dissipation per meter of cable.
