Fluid mechanics and properties.

DOE-STD-1176-2004

Compare and contrast the principle of operation and typical pumped medium of

the following types of positive displacement pumps:

Reciprocating

Rotary-screw

Vane-axial

Using the following list of system and/or pumped medium characteristics, identify

which type of pump (e.g., centrifugal, reciprocating positive displacement, rotary-

screw positive displacement) is best suited for the application.

Fluids with high viscosities

Low volume, high head

Low head, high volume

Water

Oil

Discuss the concept of pump cavitation and describe its harmful effects.
