You have to do thermal analysis of a building near an arctic observatory, which has a footprint of 8-mx 12-m and height of 4-m and oriented as shown. The ambient air temperature is -15°C and it is blowing at a velocity of 3.2 m/s from East to West parallel to the front wall. The sky temperature is -5°C. The surface temperature of the building is kept uniform at 15°C. What is the total convective heat transfer rate from the front wall of the building?

**Thermal Analysis of an Arctic Observatory Building** **Problem Statement:** You need to conduct a thermal analysis of a building located near an arctic observatory. The building has a footprint of 8 meters by 12 meters and a height of 4 meters, oriented as shown in the diagram. The ambient air temperature is -15°C, and the wind is blowing at a velocity of 3.2 m/s from east to west, parallel to the front wall. The sky temperature is -5°C, and the surface temperature of the building is maintained at 15°C. Determine the total convective heat transfer rate from the front wall of the building. **Solution:** The total convective heat transfer rate from the front wall is calculated to be 11668 W. **Diagram Explanation:** The diagram is a 3D representation of the building, showing its orientation with respect to the cardinal directions: - The building is rectangular with the longer side (12 meters) oriented from west to east and the shorter side (8 meters) from south to north. - The height of the building is 4 meters. - The wind direction is shown, blowing from the east towards the west against the building’s front wall (facing east).
