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
