60. Which are suitable for situations where there is a large temperature difference between the two streams? A U-tube heat exchanger B floating-head heat exchanger C shell-and-tube heat exchanger with expansion joints D fixed-tube-sheet heat exchanger. The answer is ABC, but I couldn’t find the source. I wonder if this question is intended to test which heat exchangers have thermal compensation capabilities
You’re thinking right. The fixed tube sheet type experiences high thermal stress and is not suitable for applications with large temperature differences. Association* Question 4-14.
