%_In a shell and tube heat exchanger, triangular pitch arrangement as compared to square pitch arrangement_%

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