This paper describes the study, by use of models, of two sumps for the installation of impounding pumps at the Tilbury Dock extension.
The first design studied indicated that there would be excessive random velocity fluctuations in the area of the impeller. Modifications reduced the fluctuations to more reasonable proportions. Problems of locating the impeller in a plane of low-velocity fluctuation led to a study of a second design of sump.
The second design, with the aid of flow straightening diaphragms, produced improved flow conditions in the plane of the impellers.
