Astorage shed is constructed using 1-inch thick sheets of plywood as the walls. analyze heat transfer across one of the walls, which is 6.0 feet tall by 8.0 feet wide. on the outside of the shelter, the air temperature is 95 of, and with a strong wind, the convective heat transfer coefficient is 160 btu/h-ft2f. on the inside of the shelter, the air temperature is 72 of, but with still air, the convective heat transfer coefficient is only 18 btu/hft2-f. a. determine the three thermal resistance terms for the air (inside and outside) and plywood in this problem. (consider which resistance is the largest and which is the smallest- does it makes sense? ) b. what is the rate of heat transfer, q, from the outside air to the inside air? c. what are the temperatures on the surfaces of the plywood (toutside and tinside) you may assume 1-d, steady state heat transfer, with a constant k for the plywood (use 300 k). you may ignore radiation. when working problems, give your answer in the same unit system as the problem (i. e., english units here).
thermal conductivity of plywood is 0.12 (w/ m-k)
