Arow of regularly spaced, cylindrical heating elements is used to maintain an insulated furnace wall at 500 K. The opposite wall is at a uniform temperature of 300 K. The heating elements have a diameter of D = 10 mm and are spaced L = 40 mm apart. Wall Heating element Insulated wall The insulated wall experiences convection with air at 450 K and a convection coefficient of 200 W/m2.K. Assuming the walls and elements are black, estimate the required operating temperature for the elements, in K. Te = K
