    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 .

     · 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.
