3-23 A long, hollow cylinder with constant thermal conductivity has a constant heat supply at a rate of $q_i\mathrm{W}/{\mathrm{m}}^2$ at the inner boundary surface at $r=r_i$, while the heat is dissipated from the outer boundary surface at $r=r_0$ by convection into a fluid at zero temperature with a heat transfer coefficient $h$. Develop an expression for the steady-state temperature distribution $T(r)$ in the cylinder.
