Question 200General Subjects - 1st Asst/Chief70% to pass
Expansion tanks when used in a ship's low temperature hot water heating system may be of the open or closed type. Referring to the illustrated central-station hookup for a hot water heating system drawing, what would be the normal temperature range of the water? Illustration GS-0151
AI Explanation
The correct answer is A) 180°F to 200°F.
In a 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 lower temperatures compared to high temperature systems, which may reach up to 320°F to 360°F (option D).
The other options, B) 220°F to 240°F and C) 260°F to 280°F, are higher temperature ranges that are more characteristic of high temperature hot water heating systems, which are not the focus of the question.
