Floating head heat exchangers are used for the____________________?
Correct answer: B. Cases where temperature difference between the shell and the tubes is more (>50°C)
- A. Heat transfer between corrosive fluids
- B. Cases where temperature difference between the shell and the tubes is more (>50°C)
- C. Co-current heat transfer systems
- D. Counter-current heat transfer systems
Explanation
A floating head allows the shell and tubes to expand independently, so it is suitable when the shell-to-tube temperature difference is large, commonly taken as over about 50°C. It also facilitates tube-side cleaning, but the temperature-difference condition is the intended choice here.
