Hollow cylinder of inner radius and outer radius is heated with uniform flux Ri qoi at its inner surface. The lower half of the cylinder is insulated and the upper half exchanges heat by convection and radiation.

The heat transfer coefficient is h, ambient temperature T, surroundings temperature and surface emissivity is T. fsurH Neglecting axial conduction and using a simplified radiation model, write the steady state heat equations and boundary conditions.
