In a shell and tube type heat exchanger, the floating tube bundle heat arrangement is used________________?
Correct answer: B. In high range of temperature differences
- A. In low range of temperature differences
- B. In high range of temperature differences
- C. Because of its low cost
- D. To prevent corrosion of the tube bundles
Explanation
A floating tube bundle allows the tubes to expand and contract independently of the shell, so it is preferred when the temperature difference is high. This prevents excessive thermal stresses that could damage fixed-tube arrangements.
