Thermodynamics

If θi is the inversion temperature, θn is the neutral temperature, θc is the temperature of the cold junction, then

  1. θi - θc = 2θn
  2. θc - θi = 2θn
  3. θi + θc = θn
  4. θn = (θi + θc)/2

Answer

The neutral temperature is related to inversion and cold junction temperature by the following expression:

θn = (θi + θc)/2

The correct option is D.
