Homework Help: Find light bulb surface temp from temperature measurements

  1. Nov 20, 2013 #1
    1. The problem statement, all variables and given/known data
    I have 3 data points of steady state temperature at 3 locations some distance away from a bulb, I need to calculate the temperature of the surface of the bulb. It would be best to assume the bulb is a hemispherical radiation source, based on the experiment set-up

    2. Relevant equations


    3. The attempt at a solution
    I am assuming the temperature distribution is not linear so using a line to fit the data then backing out the temp would not give an accurate result.

    I don't think that will work at all.
    If you can find a reasonable shape for the temperature distribution (based on a simulation or whatever), you can fit it - it is certainly not a straight line, but that does not matter for the fit.
