Web8 nov. 2024 · The radiative heat transfer outside is given by (2) Q = π D L ϵ σ ( T o 4 − T ∞ 4) where T ∞ is the surroundings temperature far from the surface, σ is the Stefan-Boltzmann constant and ϵ is the emissivity of the tube surface. So, knowing Q, you can use Eqn. 2 to get T 0, and then use Eqn. 1 to get T i. Share Cite Improve this answer Follow
