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 Can accomodate less number of tubes for a given shell diameter Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Results in higher shell side pressure drop Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Can accomodate less number of tubes for a given shell diameter Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Results in higher shell side pressure drop ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design The centre to centre distance between two consecutive baffles in a shell and tube heat exchanger is called the baffle pitch or baffle spacing, which is more than 1/5th the I.D. of the shell. Which of the following is not a function of the baffles? To reduce the induced vibration in the tubes To increase the residence time of shell side fluid To provide support to the tube bundle To increase the tube side heat transfer co-efficient by inducing turbulence To reduce the induced vibration in the tubes To increase the residence time of shell side fluid To provide support to the tube bundle To increase the tube side heat transfer co-efficient by inducing turbulence ANSWER DOWNLOAD EXAMIANS APP
