Method of Molerus and Wellman to Compute the Pressure Drop of Slurry Transport in Horizontal Pipes

In the literaturey many methods for the calculation of pipeline hydraulic transport of solids have been published. Their degree of exactness and applicability is variabie and therefore it is hard to the designer to make a convincible decision regarding their practical use. A new concept for the computation of slurry hydraulic transport in horizontal pipes proposed by O. Molerus and P. Wellmann based on numerous measurement data seems to provide a practicle method to predict the head loss in slurry pipeline transport. In this report the new method is introduced and a number of new experimental results to verify the new concept. Furthermore some suggestions are presented te impreve the new methed.
