A furnace wall made up of 7.5 cm of fire plate and 0.65 cm of mild steel plate. Inside surface exposed to hot gas at 650oC and outside air temperature 27oC. The convective heat transfer co-efficient for inner side is 60 W/m2K.
The convective heat transfer co-efficient for outer side is 8W/m2K. Calculate the heat lost per square meter area of the furnace wall and also find outside surface temperature.
