Hydraulic Problems Encountered in Intake Structures of Vertical Wet-Pit Pumps and Methods Leading to Their Solution

The design of intake channels and tunnels for the efficient operation of wet-pit pumps is considered. Basically the problem is that of determining the flow pattern and losses in the suction intake and predicting their combined effect on the pump performance. Because of long distances, obstructions, and diversions, faulty flow often occurs. The resulting difficulties are explained and the methods employed in solving the attendant problems are outlined.
