3. Cost of Pumping Energy
In a slurry transport pipeline the pumping energy should be sufficient enough to overcome the losses
taking place in the pipeline.
The losses in a pipeline comprises of two parts:
• Major losses
• Minor losses
The major losses in the pipeline are due to the friction between solid and liquid phases. The minor
losses are because of the presence of valves, bends and other flow obstruction devices. Major losses are
quite high as compared to minor losses because the total length of the pipelines is higher than to be
compared with the number of pipe fittings being installed in the system. Here, only the major losses are
considered since it is assumed that overall length of the pipeline is sufficiently high.
