homogeneous resistance wire

A long homogeneous resistance wire of radius ro = 0.6 cm and thermal conductivity k = 15.2 W/m·K is being used to boil water at atmospheric pressure by the passage of electric current. Heat is generated in the wire uniformly as a result of resistance heating at a rate of 16.4 W/cm3. The heat generated is transferred to water at 100°C by convection with an average heat transfer coefficient of h 5 3200 W/m2·K. Assuming steady one-dimensional heat transfer,

(a) express the differential equation and the boundary conditions for heat conduction through the wire, (b) obtain a relation for the variation of temperature in the wire by solving the differential equation, and (c) determine the temperature at the centerline of the wire.
