Q1 Passage of an electric current through a long conducting rod of radius r, and thermal conductivity k, results in uniform volumetric heating at a rate of 4. The conduct- ing rod is wrapped in an electrically nonconducting cladding material of outer radius r, and thermal conduc- tivity ke, and convection cooling is provided by an adjoining fluid. Conducting rod, ġ, k, Th Cladding, ke For steady-state conditions, write appropriate forms of the heat equations for the rod and cladding. Express ap- propriate boundary conditions for the solution of these equations.
