Question 435General Subjects - Assistant Engineer

The correct answer is A) 180°F to 200°F. In a ship's low temperature hot water heating system, the normal temperature range of the water is typically between 180°F and 200°F. This is because low temperature hot water heating systems are designed to operate at relatively low temperatures, as opposed to high temperature systems which can reach much higher temperatures. The other options are incorrect because they represent temperature ranges that are too high for a low temperature hot water heating system. Option B (220°F to 240°F) and Option C (260°F to 280°F) are more appropriate for high temperature systems, while Option D (320°F to 360°F) is well above the typical operating range for any hot water heating system on a ship.
