A row of regularly spaced cylindrical heating elements is used to maintain an insulated furnace wall at
Question:
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. 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.
