N2 - Integrated frame of both stability and well-posedness analyses is shown to predict the complete stratified/nonstratified transitional boundary over wide ranges of conduit size. It is shown that the stabilizing effects of surface tension associated with practically finite wave lengths must be considered. This explains the basic defficiency of all previous analyses which employed single stability criteria of infinite long waves. The range of 'small diameters' conduits, regarding flow pattern transition, is identified by Eotwös number smaller than unity.
