← ScienceWhich outcome accompanies a centrifugal pump operating far beyond design?
A)Increased head loss and cavitation✓
B)Increased volumetric efficiency overall
C)Reduced impeller wear consequently
D)Stable predictable discharge pressure
💡 Explanation
Increased operation beyond design flow creates extreme turbulence. The turbulence initiates significant increases in head loss, that also may contribute to liquid cavitation, because a dramatic pressure drop occurs, rather than other efficiency improvements across the impeller.
