An electrical heater is attached to the outside of the wall to prevent heat loss from a fluid-vessel. Passing a current through the heater yields a constant rate of heat generation, H_v. The bulk temperature and heat transfer coefficient inside the vessel are T_i and h_i, respectively. The outside values are T₀ and h₀, where T₀ i. The thermal conductivity in the wall is k_w, and in the heater k_h. Assume that the steady-state temperature is a function of x only. Sketch the heat flux profile in the range -LW w h in the limits of Bi = h₀L_h/k_h 1 and Bi 1.
