A gas chamber is to be designed to separate two gases with the following specifications: Hot gas temperature 1145°C Cold gas temperature 45°C Hot gas heat transfer coefficient 230 W/m² K Cold gas heat transfer coefficient 290 W/m² K Metal wall thermal conductivity 115 W/m K If the maximum temperature of the wall on the hot side does not exceed 545°C, using thermal resistance concept, what thickness should the metal wall between the hot gas and cold gas be in mm?
