QUESTION 2 Copper fins, 2.1 cm long and 2.1 mm in diameter, are attached to a base plate at 75 °C. A fan blows air through and around this fins at 29 °C providing an average convection coefficient of 21 W m-2 K-1. Estimate the heat dissipated through each of these fins, in milliwatt (mW). Assume negligible heat transfer though the tips. The conductivity of copper may be taken to be 400 W m-1 K-1.
You have to do thermal analysis of a building near an arctic observatory, which has a footprint of 8-mx12-m and height of 4-m and oriented as shown. Because the wind direction and velocities are different on each side wall, the convection coefficient for each wall and roof are different. They are as follows h North 5 W/m².K, h South 24 W/m².K, 15 W/m².K, hEast hwest 12 W/m².K, and hRoof = 30 W/m².K, where the subscript indicate the corresponding wall/roof (for example, North is the convection coefficient for the North-facing wall). The ambient air temperature is -15°C. The sky temperature is -20°C. The solar irradiation is 350 W/m², which can be considered to be falling only on the roof and not on the walls. The surface temperature of the building is 10°C. Neglect heat transfer through the ground. What is the total heat transfer to/from the building? Is the building losing or gaining heat? What is the dominant mode of heat transfer? What is the ratio between the heat transfer rates…
