Consider a spherical container of inner radius r1, outer radius r2, and thermal conductivity k. Express the boundary condition on the inner surface of the container for steady one-dimensional conduction for the following cases: (a) specified temperature of50°C, (b) specified heat flux of 45W/m2 toward the center, (c) convection to a medium at T∞ with a heat transfer coefficient of h.
