Question 434General Subjects - Assistant Engineer
70% to passExpansion tanks when used in a ship's low temperature hot water heating system may be of the open or closed type. In a closed type system, what would be the normal temperature range of the water?
A180°F to 200°F
B220°F to 240°F
C260°F to 280°F
D320°F to 360°F
AI Explanation
The correct answer is B) 220°F to 240°F. In a closed-type low temperature hot water heating system, the normal temperature range of the water is typically between 220°F and 240°F. This is because in a closed system, the water is contained and does not have direct contact with the atmosphere, allowing it to reach higher temperatures than an open system where the water is exposed to ambient air. The other answer choices are incorrect because they represent temperature ranges that are either too low (A) or too high (C and D) for a typical closed-type low temperature hot water heating system on a ship.
