An Analytical Study on Centrifugal Pump Performance Under Different Rotational Speeds

Understanding the local flow characteristics of centrifugal pumps under diverse piping system flow conditions is essential. This study conducts analytical research on a radial flow single-stage centrifugal pump operating at five different rotational speeds: 1000, 1200, 1400, 1600, and 1800 rpm. All equations are implemented in MATLAB to forecast pump performance. Additionally, losses have been accounted for, including leakage loss and impeller loss. The pump's discharge, head, efficiency, and the power necessary to operate the pump were evaluated. This study can be used for any type of fluids. However, only a single phase is involved. The petroleum and chemical industries may gain advantages from the results of this research.
