Along cylinder (not a cylindrical shell) of radius ro undergoes radial-one dimensional, steady-state conduction. there is a uniform rate of thermal energy generation per unit volume ˙q and a constant thermal conductivity k. if the temperature of the outer surface is ts, find the temperature distribution across the cylinder and the rate of heat transfer per unit length from the cylinder. (key point - what is the second boundary condition? )
