Electrically heated draw batch furnaces are commonly used in the heat treatment industry. Consider a draw batch furnace front made of a 20-mm thick steel plate with a thermal conductivity of 37 W/m·K. The furnace is situated in a room with surrounding air temperature of 20°C and an average convection heat transfer coefficient of 10 W/m2·K. If the inside surface of the furnace front is subjected to uniform heat flux of 5 kW/m2 and the outer surface has an emissivity of 0.30, determine the inside surface temperature of the furnace front in K. (Round your answer up to 2 decimal places.) The Stefan–Boltzmann constant is 5.67 × 10-8 W/m2 . K4
