Centrifugal pumps are being used increasingly for transportation of slurries through pipelines. To design a slurry handling system it is essential to have a knowledge of the effects of suspended solids on the pump performance. A new correlation to predict the head reduction factor for centrifugal pumps handling solids has been developed. This correlation takes into account the individual effect of particle size, particle size distribution, specific gravity and concentration of solids on the centrifugal pump performance characteristics. The range of validity of the correlation has been verified by experiment and by using experimental data available from the literature. The present correlation shows better agreement with the experimental data than existing correlations.

The performance of two centrifugal slurry pumps has been reported for three solid materials having different particle size distribution (PSD) in terms of head, capacity, and power characteristics. The results have shown that the values of head and efficiency ratios are not only dependent on solid concentration but are also affected by PSD of the solids and properties of the slurry. The addition of fine particles in the slurry of coarser material leads to reduction in the additional losses that occur in the pumps due to the presence of solids. It is also observed that with the increase in the pump size, the additional losses due to presence of solids reduce.

Properties Of Composites

The separate influence of the coupling agent, aminopropyltriethoxysilane, on the physicomechanical characteristics of polypropylene- and clinoptilolite-based nanocomposites has been considered. It was established that the introduction of the coupling agent improves the properties of nanocomposites. A comparative assessment of the influence of clinoptilolite particle size on the key performance characteristics of polymeric materials is given. The regularities of changes in the properties of composites depending on the concentration of the filler are revealed.
