Question: 238 passage of an electric current through a long conduct...

Question details

2.38 Passage of an electric current through a long conduct- ing rod of radius r, and thermal conductivity k, results in uniform volumetric heating at a rate of q. The con- ducting rod is wrapped in an electrically nonconducting cladding material of outer radius ro and thermal com- ductivity k, and convection cooling is provided by an adjoining fluid. Conducting rod, á, k, Teo, h Cladding, k For steady-state conditions, write appropriate forms of the heat equations for the rod and cladding. Express appropriate boundary conditions for the solution of these equations.
