In a shell and tube heat exchanger, triangular pitch arrangement as compared to square pitch arrangement

Can accomodate less number of tubes for a given shell diameter
Results in higher shell side pressure drop
Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient
Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid

Pick out the wrong statement pertaining to the comparative evaluation of performance of the packed tower and the plate tower.

In operations involving large temperature changes. (e.g. distillation), plate towers are preferred over packed towers as the packing may be crushed due to large temperature changes
Plate tower is preferred over packed tower, if the operation involves liquids containing dispersed solids
The total weight of a dry plate tower is usually much more than that of a dry packed tower designed for the same duty
Plate tower is perferred, if interstage cooling is required to remove heats of reaction or solution
