Floating head heat exchangers are used for the____________________?

Correct answer: D. Cases where temperature difference between the shell and the tubes is more (>50°C)

A. Heat transfer between corrosive fluids
B. Counter-current heat transfer systems
C. Co-current heat transfer systems
D. Cases where temperature difference between the shell and the tubes is more (>50°C)

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.
