Baffles are used in shell-and-tube heat exchangers... to enable the shell to withstand the strong turbulent flow around the tubes. to increase the total area of the tubes over which the fluid in the shell flows. all of the above. to force a cross flow of the shell fluid over the tubes.

Solution

baffles are used to hold the tubes to prevent vibration when increasing velocity of fluid for turbulent flow hence frst option is the correct answer
