Correct
01.
Q: Identify the true statement.
A: If all the parameters are recorded immediately after the pump has been installed, you can use them as benchmark against future data.
Correct
02.
Q: What causes cavitation?
A: Cavitation occurs when water changes its state from vapour to water at low pressure.
