Process Equipment and Plant Design In a shell and tube heat exchanger, triangular pitch arrangement as compared to square pitch arrangement Results in higher shell side pressure drop Can accomodate less number of tubes for a given shell diameter 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 Results in higher shell side pressure drop Can accomodate less number of tubes for a given shell diameter 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 ANSWER DOWNLOAD EXAMIANS APP
