Question
To 8. 22 1 2 T₁ 3 1. 2. 3. 4" Common Brick 1/2" OSB Sheathing 3-1/2" x 1-1/2" (2x4) Yellow Pine Studding placed on 16" center 4. 5. 3-1/2" Figerglass Insulation 1/2" Drywall A wall of a house as shown in the accompanying sketch is 10 ft. high and 30 ft. long and has no windows. The outside heat transfer coefficient, h., is 6.0 Btu/hr ft2°F and the inside convective heat transfer coefficient hi is 1.45 Btu/hr ft²°F. 6. Calculate the heat loss through the wall if the house is heated such that the room air temperature, Ti, is 70°F on a day when the outside air temperature, T., is 0°F. State all assumptions and list the thermal resistances and thermal conductivities for each selection of the wall. For this problem, what would be the 7. value of the overall heat transfer coefficient, U? Ans: U = 0.056 Btu/hr ft2°F You are asked to design a metal hot dog holder for roasting hot dogs over an open campfire. The holder is to be designed such that while the end holding the hot dog becomes cherry red (1400°F), the other end can still be held without using an insulated handle or glove (~95°F). Design it such that it can be used even on a warm, still day, T₁ = 90°F (Assume the convective heat transfer coefficient, h, for a horizontal cylinder is uniform over the whole cylinder and equal to 4.0 Btu/hrft2°F)
