A bar of gold (bar A) is in thermal contact with a bar of copper (bar B) of the same length and area. One end of the compound bar is maintained at Th = 76.0 degree C while the opposite end is at 30.0 degree C. Find the temperature at the junction when the energy flow reaches a steady state. Your response differs from the correct answer by more than 10%. Double check your calculations.

5. A 1.5 mm diameter thermocouple is inserted through a pipe wall maintained at 45 C to measure the temperature of a fluid flowing in the pipe. The thermocouple protrudes 12 mm into the fluid, and the convection heat transfer coefficient over the thermocouple is approximated as 500 W/m℃. The thermocouple indicates a temperature of 100 °C. The effective thermal conductivity of the thermocouple is 19 W/m-°C. Consider steady, one-dimensional conduction in the thermocouple,...
