VELOCITY STUDY OF CENTRIFUGAL PUMP IMPELLERS (Technical ...
The maximum velocities of the lOOA, 200A, and 300A pumps are between 39 and fps with the exception of the lOOA absolute discharge velocity which is fps. For large slurry pumps, it is recommended that lower speeds be used in order to reduce the impeller relative velocities.

Centrifugal pump design: Three benchmark problems for many ...
By means of velocity triangles for the °ow in the impeller in and outlet, the pump equation can be interpreted and a theoretical lossfree head and power consumption can be calculated. Velocity triangles can also be used for prediction of the pump's performance in connection with changes of speed, impeller diameter and width.

Pump Theory
If torque and angular velocity are of like sign, work is being done on the fluid (a pump or compressor). If torque and angular velocity are of opposite sign work is being extracted from the fluid (a turbine). Thus for the design aspect of turbines and pumps, the Euler equations are extremely useful. Example: Pump .

The Role of Liquid Velocity in Centrifugal Pump Systems ...
· Well, centrifugal pumps work by transforming kinetic energy into fluid velocity by means on an impeller. At its most basic, an impeller is a rotating implement connected to a shaft — or, in the case of our pumps, spun by use of magnets — that uses an outwardpushing movement to move fluid through the system.
