Scale-up of critical velosity and wear rate of slurry pipeline

A common practice in designing slurry pipeline is scaling up data from model test to real flow situation. Considerations are given to the problems involved in the adequacy of scale up. Critical velosities to maintain solids in suspension and wear rate of pipe are discussed. The effect of magnification on the accuracy of scale up is reviewed. Also, various scale up techniques using extensive data are veritified for its feasibility.
