Consider two long, slender rods of the same diameter but different materials. One end of each rod is attached to a base surface maintained at 100°C, while the sur- faces of the rods are exposed to ambient air at 20°C. By traversing the length of each rod with a thermocou- ple, it was observed that the temperatures of the rods were equal at the positions XA = 0.15 m and x³ = 0.075 m, where x is measured from the base surface. If the thermal conductivity of rod A is known to be kA = 70 W/mK, determine the value of kB for rod B. XA=0.15m T-100°C- f -TA=TB XB=0.075m Rod A, KA=70W/m-K Too=20°C -Rod B, kB
