Find the emissivity of the metal part

Reference no: EM131275969

Using the results of Prob. 8.47, determine the true metal temperature when the pyrometer indicates 450?C and the uncertainty in this temperature.

Prob. 8.47

The radiation from a metal part is measured with a pyrometer which indicates a temperature of 300?C. The actual part temperature is measured with a thermocouple which indicates 315?C. Both measurements have an uncertainty of ±1?C. From these measurements, determine the emissivity of the metal part and its uncertainty.
