Effect of Specular Reflexions on the Radiation Flux from a Heated Tube

Abstract

IN my communication under the above title1 there appears an error in expression (7) for F L . The expression should read: Taking the radiation from a black surface as reference, one can then show that the deficit from it of the flux of radiation from the mouth of a uniformly heated cylinder of length L, closed at the other end, is (1 − ɛ) times the corresponding deficit for the flux from the mouth of a cylinder of same diameter and of length 2L, but open at both ends.
