A 2-kW resistance heater wire whose thermal conductivity is k = 10.4 Btu/h•ft•R has a radius of ro = 0.06 in and a length of L = 15 in, and it is used for space heating. Assuming constant thermal conductivity and one-dimensional heat transfer, express the mathematical formulation (the differential equation and the boundary conditions) of this heat conduction problem during steady operation. Do not solve.
