A long metal sheet that can be approximated as a blackbody is being conveyed through a water
Question:
A long metal sheet that can be approximated as a blackbody is being conveyed through a water bath to be cooled. In order to prevent thermal burn on people handling the sheet, it must exit the water bath at a temperature below 45°C. A radiometer is placed normal to and at a distance of 0.5 m from the sheet surface to monitor the exit temperature. The radiometer receives radiation from a target area of 1 cm2 of the metal sheet surface. When the radiometer detects that the metal sheet temperature is not below 45°C, an alarm will go off to warn that the sheet is not safe to touch. Determine the irradiation on the radiometer that the warning alarm should be triggered.
Step by Step Answer:
To determine the irradiation on the radiometer that the warning alarm should b...View the full answer
