Determine the emissivity value of the gas (). And calculate the net heat transfer rate in kW/m2. And determine the absorptivity value of the gas (a). There is a gas mixture containing 35% HO and 65% N between two large parallel black plates that are 1.25 m apart. The gas mixture has a temperature of 1200 K and a total pressure of 1 atm. Both plates have a temperature of 127C. Note: The two plates only see each other.
