Part 3/7:
Once the initial setups were complete, Alan and Ryan tested the emissivity of several materials, including cast alumina and various high-emissivity paints. They paid careful attention to the heat levels and adjustments, trying to reach and maintain the required temperatures for accurate measurements.
They utilized a pyrometer, which needed to reach around 875 degrees Fahrenheit to function correctly. A significant part of their task involved capturing data while monitoring fluctuations in temperature and power input throughout the session. They shared insights about the scientific principles underlying their measurements, such as how power increases with the square of the voltage.
