Includes bibliographical references (pages 22-24). "The prevention of vortices at pump intakes is an important design consideration. Vortices at intake structures cause serious changes in flow patterns, vibrations, objectionable noise, increase energy losses and decrease pumping efficiency. The effective design of pump intakes requires the use of physical scale models to ensure that proper measures are taken to eliminate the formation of vortices. This report presents information which will make it possible to obtain a satisfactory scale model to test different intake design schemes"--Management Perspective.
