Problem 1. bar shown below, determine the temperatures at Nodes 2 and 3. Assume 1-D heat transfer that only occurs in the x-direction as the upper and lower 1-D Heat Transfer with Conduction. For the 1-D composite boundaries of the elements are insulated. Assume the cross-sectional area is the same for all elements, A=0.01 m?. For Element 1, let the thermal conductivity be 100 W/(m °C). For Element 2, let the thermal conductivity be 110 W/(m °C). For Element 3, let the thermal conductivity be 120 W/(m °C). The left end of the bar has a constant temperature of 120°C (at Node 1) and the right end has a constant temperature of 276 °C (at Node 4).

bar shown below, determine the temperatures at Nodes 2 and 3. Assume 1-D
heat transfer that only occurs in the x-direction as the upper and lower
1-D Heat Transfer with Conduction. For the 1-D composite
boundaries of the elements are insulated. Assume the cross-sectional area is the
same for all elements, A=0.01 m?. For Element 1, let the thermal conductivity be
100 W/(m °C). For Element 2, let the thermal conductivity be 110 W/(m °C). For
Element 3, let the thermal conductivity be 120 W/(m °C). The left end of the bar
has a constant temperature of 120 °C (at Node 1) and the right end has a constant
temperature of 276 °C (at Node 4).
