Difficulty: MediumDirect Fact Retrieval

Read the following technical passage:

During daily operation of shipboard centrifugal fuel oil purifiers, operators must monitor the operating water pressure to maintain the liquid seal. If the operating water pressure falls below 25 pounds per square inch (psi) during fuel separation, the sliding bowl bottom drops prematurely, discharging unprocessed fuel directly into the sludge collection tank. During initial startup flushes, the manual three-way operating valve must remain open for at least 15 seconds to verify full bowl closure before introducing raw fuel.

Based on the passage, a drop in operating water pressure below 25 psi during fuel separation causes the sliding bowl bottom to drop prematurely.

Answer: Answer

Answer

True
The passage explicitly confirms that when operating water pressure falls below 25 psi during separation, the sliding bowl bottom drops prematurely.

Step-by-Step Solution

1
Identify the key condition and mechanical effect presented in the statement.
The target statement asserts that operating water pressure falling below 25 psi causes the sliding bowl bottom to drop prematurely.
Direct fact retrieval requires finding the exact sentence in the text addressing operating water pressure and its direct operational consequence.
2
Scan the passage for the specific pressure metric and verify the stated outcome.
The passage directly confirms: 'If the operating water pressure falls below 25 pounds per square inch (psi) during fuel separation, the sliding bowl bottom drops prematurely...'
Matching the explicit factual details verifies that the statement is directly supported by the text.
