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 Results in higher shell side pressure drop 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 Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Results in higher shell side pressure drop 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 ANSWER DOWNLOAD EXAMIANS APP

Process Equipment and Plant Design When one of the fluids is highly corrosive and has fouling tendency, it should Perferably flow outside the tube Preferably flow inside the tube for its easier internal cleaning Flow at a very slow velocity Flow outside the tube, when the flow is counter-current and inside the tube when the flow is co-current Perferably flow outside the tube Preferably flow inside the tube for its easier internal cleaning Flow at a very slow velocity Flow outside the tube, when the flow is counter-current and inside the tube when the flow is co-current 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 provide support to the tube bundle To increase the residence time of shell side fluid To reduce the induced vibration in the tubes To increase the tube side heat transfer co-efficient by inducing turbulence To provide support to the tube bundle To increase the residence time of shell side fluid To reduce the induced vibration in the tubes To increase the tube side heat transfer co-efficient by inducing turbulence ANSWER DOWNLOAD EXAMIANS APP
