Lab questions:

1) why is the initial inlet line pressure below atmospheric pressure in both the cavitation and air entrainment tests?

2) Explain the reason the pressure drops in the pump inlet line as the cavitation test value is closed.

3) why must the inlet line pressure be seversl psi below normal operting pressure before cavitation begins?

4) what causes the noise when a pump cavitates?

5) Describe what can mechanically happen to a pump if it continues to be operated while cavitating.

6) ehat happens to the inlet line pressure as the air entrainment valve is opened? Explain why this occurs.

7) what causes noisy pump operation when air enters the inlet line?

8) List several factors that could cause pump cavitation.

9) list several factors that could cause air entrainment at the pump inlet line.

10) what procedures would you use to identify the cause of noisy pump operation that may be caused by cavitation or air entrainment at hte inlet line?
