A long homogeneous resistance wire of radius ro = 2 cm, and thermal conductivity k = 25 W/m°C is being used to boil water. Heat is generated in the wire uniformly as a result of resistance heating at a rate of q'=10x105 W/m. If the outer surface temperature of the wire is measured to be Ts = 120 °C, obtain a relation for the temperature distribution, and determine the temperature at the centerline of the wire for steady operating conditions
