10. A flow-through combustion chamber consists of long, 15-cm-diameter tubes immersed in water. Compressed air is routed to the tube, and fuel is sprayed into the compressed air. The combustion gases consist of 70 percent N2, 9 percent HO, 15 percent O2, and 6 percent CO2 , and are maintained at 1 atm and 1500 K. The tube surfaces are near black, with an emissivity of 0.9. If the tubes are to be maintained at a temperature of 600 K, determine the rate of heat transfer from combustion gases to tube wall by radiation per m length of tube.

Hi, this is an design and essay problem. From thermodynamics You need to assume the temperature of the black surface to find the working potential. The Sun supplies electromagnetic energy to Earth. It appears to have an effective temperature of approximately 5,800 K. On a clear summer day in North America, the incident energy on a surface facing the Sun is approximately 0.95 kW / m2. Electromagnetic solar energy can be converted into thermal energy by being absorbed by a darkened surface. How could you characterize the work potential of solar energy when it is to be used to produce work?
