Problem 3 Part B 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 effectiveness of the fin ME3313_Exam1_FormulaSheet.pdf ME3313_FinConfigurations_Cengel_Table3_3.pdf

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

Problem 4 A 10-m long copper pipe (k = 400 W/m-K) has an outer diameter of 25.4 mm and a thickness of 1.65 mm. A diagram of the cross-sectional view of the pipe is provided below. Inside the pipe, refrigerant flows at 10 °C with a heat transfer coefficient of 200 W/m2-K. Outside the pipe, air flows at 35 °C with a heat transfer coefficient of 10 W/m2-K.   Using the thermal resistance method for cylindrical arrangements, determine the temperature of the inner surface of the pipe ME3313_Exam1_FormulaSheet.pdf

Problem 2 Part A 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.   Provide the governing differential equation and boundary conditions for the 1-D, steady state conduction through the wall. Include this equation in your Work Submission. As a placeholder here, type “conduction.” ME3313_Exam1_FormulaSheet.pdf
