A composite wall is comprised of two large plates separated by sheets of refractory insulation. In the installation process, the sheets of thickness L = 50 mm and thermal conductivity k = 0.05 W/mK are separated at 1-m intervals by gaps of width w = 10 mm. The hot and cold plates have temperatures and emissivities of T1 = 400 deg C, emissivity1 = 0.85 and T2 = 35 deg C, emissivity2 = 0.5, respectively. Assume that the plates and insulation are diffuse-gray surfaces. %3D Determine the heat loss by radiation through the gap per unit length of the composite wall (normal to the page). Recognizing that the gaps are located on a 1-m spacing, determine what fraction of the total heat loss through the composite wall is due to transfer by radiation through the insulation gap.

The temperature of the outer surface of the roof and the walls of the shed is to be maintained at least 20°C on a quiescent night when outside temperature is 0°C and sky temperature is -15°C. What is the total heat loss heat loss from the building?Ignore the heat transfer through the ground. Assume the emissivity of the walls and roofs is 0.75.
A large number of long tubes, each of diameter D,are placed parallel to each other and at a center-to-center distanceof s. Since all of the tubes are geometrically similarand at the same temperature, these could be treated collectivelyas one surface (Aj) for radiation heat transfer calculations., the tube-bank (Aj) is placedopposite a large flat wall (Ai) such that the tube-bank is parallelto the wall.(a) Calculate the view factors Fij and Fji for s = 3.0 cmand D = 1.5 cm.(b) Calculate the net rate of radiation heat transferbetween the wall and the tube-bank per unit area ofthe wall when Ti = 900°C, Tj = 60°C, «i = 0.8, and«j = 0.9.(c) A fluid flows through the tubes at an average temperatureof 40°C, resulting in a heat transfer coefficientof 2.0 kW/m2·K. Assuming Ti = 900°C, «i = 0.8,and «j = 0.9 (as above) and neglecting the tube wallthickness and convection from the outer surface,calculate the temperature of the tube surface in steadyoperation.
