Performance and Internal Flow Characteristics of a Very Low Specific Speed Centrifugal Pump
TL;DR: In this article, the authors investigated the internal flow characteristics and its influence on the performance of a very low specific speed centrifugal pump and showed that large reverse flow at the semi-open impeller outlet decreases absolute tangential velocity considerably which in turn decreases the pumping head.
