Consequence analysis hole size

Stahl, M., Kenady, K., 2011. A frequency based approach to hole size selection for consequence analysis. 

Consequence Analysis to Achieve a Conservative Result. All models, including consequence models, have uncertainties. These uncertainties arise due to (1) an incomplete understanding of the geometry of the release, that is, hole size, (2) unknown or poorly characterized physical properties, (3) a poor understanding of the chemical or release process, and (4) unknown or poorly understood mixture behavior, to name a few.
