This requires an average value of viscosity representing the variable non-Newtonian viscosities. To determine such an average viscosity, two approaches exist in the literature: the use of a Bingham plastic viscosity and the use of the apparent viscosity. Results from these two approaches are not in agreement. This study evaluates the two approaches using two independent datasets, obtained from three pumps and three fluids. Results indicate that using the apparent viscosity approach gave better head prediction and using the Bingham plastic viscosity resulted in better efficiency prediction.","author":[{"@context":"https://schema.org","@type":"Person","name":"Veruscha

The process of derating the performance of a given centrifugal pump at a fixed impeller rotational speed involves the estimation of the pump performance through the reduced head, throughput and efficiency compared with water alone. In 1983, the Hydraulic Institute in the USA provided a method for derating pumps for Newtonian viscous liquids, and the approach has been incorporated into the 2015 ANSI/HI standard. By contrast, while there have also been some significant experimental studies in the last 20 years or so which report the deration of centrifugal slurry pumps when pumping various non-Newtonian slurries, some of which include various approaches to pump deration for this slurry type, a standardised and commonly-accepted method has not yet emerged.

of a centrifugal pump which was designed at 3300 rpm and 40 l/min for water were examined numerically. A numerical analysis using Computational Fluid Dynamics methodology was carried out. Water and three different non-Newtonian fluids of CMC 0.4%, CMC 0.3% and CMC 0.2% which derived from Carboxy Methyl Cellulose (CMC) solution were used in the analyses. The analyses were performed with the flow rates range of 10-80 l/min and rotor speed values of 3300 rpm and 1400 rpm. The results showed that the performance of the pump with non-Newtonian fluids was better than the water at 3300 rpm, contrary to 1400 rpm.</p><div class="ds-related-work--ctas"><button
