Question:
This experiment is conducted to determine the emissivity of a certain material. A long cylindrical rod of diameter D1 = 0.01 m is coated with this new material and is placed in an evacuated long cylindrical enclosure of diameter D2 = 0.1 m and emissivity ε2 = 0.95, which is cooled externally and maintained at a temperature of 200 K at all times. The rod is heated by passing electric current through it. When steady operating conditions are reached, it is observed that the rod is dissipating electric power at a rate of 8 W per unit of its length and its surface temperature is 500 K. Based on these measurements, determine the emissivity of the coating on the rod.
