question

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 CO_2. The con-tainer radiates 65% of the heat liberated due to com-bustion. Determine the radiation area required if the container attains a temperature of 1500°F. The tempera-ture of the surroundings is 150°F and the heat of com-bustion of CO to CO_2 is 4350 Btu/lb CO. Assume the con-tained and the surroundings to be black bodies.
