Predicting Friction Headloss in Slurry Pipelines.

摘要

This document compares five different approaches to prediction of the loss of pressure due to friction when a slurry is flowing in a pipe. These theories,which are mainly empirical,are based upon laboratory tests in small pipes with some existing data on slurries in larger pipes. The results are not conclusive,but the Newitt approach was chosen for further investigation because it most nearly represented data for larger pipe sizes.
