Calculate the thermal gradient of the line for reference. Use the two readings T3 and T5, the given distance between them, the heater power, and the bar area with Equation 9, to calculate the thermal conductivity of the specimen. Compare it with the typical values given in Table 5. Indicate the differences and explain the differences.
