Dispersal of Dust Particles from Elevated Sources. II. Limitations of the Approximate Theory

Abstract

This paper forms a continuation of a previous one (Csanady 1955) wherein Sutton's continuous point source equations were extended to the case of heavy particles of uniform free falling speed. The solution obtained there was an approximate one; limits of validity are discussed in detail in the present paper. This discussion is preceded by a generalization of the earlier solution and two charts are presented to aid calculation of the "mirror image multiplier", the basic function of the· approximate theory.
