Question

Please provide accurate answer with proper steps

The wall of the furnace is 30.48 mm thick and is insulated from outside. Thermal conductivity of the wall material is 0.1 W/m K and the insulation material is 0.01 W/m K. The furnace operates at 650 ⁰C and the ambient temperature is 30 ⁰ Allowable temperature on the outer side of the insulation is 100⁰C. Determine the overall heat transfer by conduction per unit area occurring across a furnace wall made from clay.

If the air side heat transfer coefficient is 0.4 W/m² K, calculate the minimum insulation thickness requirement.
