Write down the question number (Example: Question F3). You must submit the PDF version of your solutions with all steps to Dropbox - Midterm for grading. No other submission will be graded. Late submission will not be graded. Question D2: The geometry of an electrical component can be approximated by the geometry shown in the figure below. The entire component is made of pure Aluminum (p=2702 kg/m, Cp = 903 J/kg-K, k 237 W/m-K). The temperature of the component is 150C when it is exposed to a convective environment (h-5 W/m-K and T-20C). (a) Calculate the Biot Number. Can you use the Lump System Approximation for this problem? (b) Calculate the temperature of the component after 10 minutes. 10 mm 10 mm 5 mm 10 mm 5 mm
