Question

what is an impeller?
a rotating component of a centrifugal pump
support system to ensure alignment
a housing unit
a unit that absorbs shock and vibrations
question 8 (1 point)
what would a pump in recirculation tell you about how it is operating?
overworked motor or running the system past its rated output
blocked intake due to decreased flow rate in pump source
failure to translate the power and absorb vibrations
insufficient pump operation due to failing motor or viscous ma

Explanation:

For the first question, an impeller is the core rotating part in centrifugal pumps that moves fluid by imparting kinetic energy. For the second question, pump recirculation occurs when the pump is moving more fluid than the system can accept, which happens when the motor is overworked or the system runs beyond its rated output. Note: The last option of Question 8 is cut off, but based on standard pump operation knowledge, the selected option is correct.

Answer:

1. A rotating component of a centrifugal pump
2. Overworked motor or running the system past its rated output
