heat transfer

- A long solid cylinder of constant thermal conductivity and radius rois initially at a uniform temperature T. For time to the peripheral surface loses heat by convection to the ambient temperature T. Answer the followings. (70%) (a) Show the governing equation and the boundary conditions as originals. (b) Redefine the temperature T(r, t) for the homogeneous boundary conditions. (c) Show the separation of variables.
