Water turbine
Reaction turbine
When the fluid is forced away from the center, or the eye of the impeller, a ____ is created thus resulting to flowing of more liquid.
centrifugal force
positive displacement
vacuum
negative displacement
It is a type of pump casing design that has an offset impeller creating a curved funnel with an increasing cross-sectional area towards the pump outlet which causes the fluid pressure to increase towards the outlet.
vortex
volute
diffuser
rotary
It is a rotating component of a centrifugal pump that accelerates fluid outward from the center of rotation, thus transferring energy from the motor that drives the pump to the fluid being pumped.
