A 2-4 heat exchanger involves__________________?
Correct answer: D. Both counter and parallel-flow of the fluids
- A. Only counter-flow of fluids
- B. Only parallel-flow of fluids
- C. Smaller pressure drop compared to 1-2 exchanger
- D. Both counter and parallel-flow of the fluids
Explanation
In a 2-4 exchanger, the multiple tube passes and shell-side flow arrangement produce both parallel-flow and counter-flow sections. Therefore, it is not exclusively either flow pattern.
