Question 169Motor Plants - QMED70% to pass
When monitoring a heavy fuel oil treatment plant, what would be an indication that the treatment plant throughput volume is less than the main engine consumption?
AI Explanation
The correct answer is B) The HFO day tank will continuously drop in level.
If the heavy fuel oil (HFO) treatment plant throughput volume is less than the main engine consumption, the HFO day tank level will continuously drop. This is because the day tank is being depleted faster than it is being replenished from the HFO treatment plant, indicating that the plant's throughput is insufficient to meet the engine's fuel demand.
The other options are incorrect because: A) The HFO settling tank level dropping continuously would not indicate the issue, as the settling tank is not directly connected to the day tank. C) and D) describe situations where the tank levels would rise, which is the opposite of what would occur when the treatment plant throughput is lower than the engine consumption.
