A gas containing 0.05 mass fraction of CO flows into a container at a rate of 250 lb/hr, where it is mixed with preheated air to oxidize the CO to CO2. The container radiates 65% of the heat liberated due to combustion. Determine the radiation area required if the container attains a temperature of 1500F. The temperature of the surroundings is 150F and the heat of combustion of CO to CO2 is 4350 Btu/lb CO. Assume the contained and the surroundings to be black bodies
