Slurry transport is still as much a black art as it is a science. The analysis tools used by Solid Advantage Consultants combines the latest science with empirical knowledge both from work done by others and from Solid Advantage's experience.
This presentation displays the analysis process and the breadth of tools used to analyze slurry gravity flow and pumping systems.
Please feel free to contact me regarding any questions you may have with the presentation or the methods used.
