Q: What causes cavitation?
A: Cavitation occurs when water changes its state from vapour to water at low pressure.
Q: What causes cavitation?
A: Cavitation occurs when water boils at 212°F and changes its state from water to vapour at normal atmospheric pressure.
01: Cavitation occurs when water changes its state from vapour to water at low pressure.
02: Cavitation occurs when water boils at 212°F and changes its state from water to vapour at normal atmospheric pressure. Your answer
03: Cavitation occurs when water flows through a pipe and a valve is closed quickly at a low atmospheric pressure

Q: Identify the false statement.
A: Cavitation can occur when water is flowing in a pipe and a valve is closed too quickly.
Q: Identify the false statement.
A: The MP204 device can protect the pump motor against all possible disturbances that may occur.

Q: Identify the true statement.
A: In deep-well pumps, you should check whether the pressure gauge is installed directly at the pump discharge.
01: In deep-well pumps, you should check whether the pressure gauge is installed directly at the pump discharge. Your answer
02: Online monitoring equipment does not check if a parameter has changed or exceeded a preset limit.
03: If all the parameters are recorded immediately after the pump has been installed, you can use them as benchmark against future data.
