Excessive water in an operating lube oil system can be detected by _______________.
AI Explanation
The correct answer is C) the amount of water discharging from the lube oil purifier.
The presence of excessive water in the lube oil system can be detected by observing the amount of water being discharged from the lube oil purifier. The lube oil purifier is designed to remove water and other contaminants from the lube oil, and an increased amount of water discharged from the purifier would indicate that there is an excessive amount of water present in the system.
The other answer choices are not as reliable indicators of excessive water in the lube oil system. Sounding the lube oil settling tank (A) may not detect the water if it is distributed throughout the system, checking the oil temperature (B) may not always be a reliable indicator, and examining the lube oil strainers (D) may not directly indicate the presence of excessive water.
