4. A row 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 (2) Wall 300K Heating element Insulated wall 500 K 20 10mm The insulated wall experiences convection with air at 450 K and a convection coefficient of 200 W/m2K Assuming the walls and elements are black, estimate the required operating temperature for the elements.
