Process Equipment and Plant Design In a shell and tube heat exchanger, the shortest centre to centre distance between the adjacent tubes is Called tube clearance Always less than the diameter of the tube Called tube pitch None of these Called tube clearance Always less than the diameter of the tube Called tube pitch None of these 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 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 Can accomodate less number of tubes for a given shell diameter Results in higher shell side pressure drop ANSWER DOWNLOAD EXAMIANS APP
