You are performing an experiment to validate the Stefan Boltzmann equation. What irradiance would you measure at a temperature of 109C? The emissivity of your thermal heat source is 0.81 and your thermopile measures 0 W/m2 at 27 C when directed towards a blackbody. Submit your answer in units of W/m2, do not include the units in your answer.
Answer tolerance is +/- 0.2%.
3. The Attempt at a Solution
I presume I have to work out a correction factor like this:
Then calculate measured irradiance:
Then I have to add the correction factor Ec to E to get the measured irradiance (Em):
Am I doing it right?
Thanks for your answers.
