Process Equipment and Plant Design In a multipass shell and tube heat exchanger, the baffles on shell side is primarily provided for Fixing the tubes Increasing pressure drop Reducing scale deposition Creating turbulence Fixing the tubes Increasing pressure drop Reducing scale deposition Creating turbulence ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger, triangular pitch arrangement as compared to square pitch arrangement 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 Results in higher shell side pressure drop Can accomodate less number of tubes for a given shell diameter ANSWER DOWNLOAD EXAMIANS APP
