Textbook Question

Chapter 2, Problem 2.51P

A spherical shell of inner and outer radii r i and r o , respectively. contains heat-dissipating components. and at a particular instant the temperature distribution in the shell is known to be of the form
T ( r ) = C 1 r + C 2
Are conditions steady-state or transient? How do the heat flux and heat rate vary with radius?
