Problem 1 Part A A plane wall is constructed of multiple materials, as shown below. Air at some temperature flows throughout the house (left-most side of the diagram, touching the drywall). The temperature of the outer wall (right-most side of the diagram) is provided along with the rate of heat transfer through the wall. The surface area normal to the heat transfer is 18 m2.   Draw the thermal resistance circuit (label all temperature locations and the heat transfer mode for the resistor) Include this drawing in your Work Submission. As a placeholder here, type “conduction.” ME3313_Exam1_FormulaSheet.pdf

Problem 2 Part D A plane wall 50 cm thick with a thermal conductivity of 40 W/m·K generates heat internally at a rate of 5,000,000 W/m3. The left side of the wall is held constant at 200 °C, and the right side of the wall is held constant at 500 °C.   Determine the location of the maximum temperature in the wall ME3313_Exam1_FormulaSheet.pdf

Problem 3 Part A A copper rod (k = 415 W/m·K) 100 mm long and 5 mm in diameter extends horizontally from a casting at 200˚C.  The rod is in an air environment with T∞ = 25˚C and h = 30 W/m2·K. Assume convection occurs at the fin tip.   Determine the heat transfer rate dispersed by the fin in Watts ME3313_Exam1_FormulaSheet.pdf ME3313_FinConfigurations_Cengel_Table3_3.pdf
