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
Process Equipment and Plant Design When one of the fluids is highly corrosive and has fouling tendency, it should Preferably flow inside the tube for its easier internal cleaning Perferably flow outside the tube Flow outside the tube, when the flow is counter-current and inside the tube when the flow is co-current Flow at a very slow velocity Preferably flow inside the tube for its easier internal cleaning Perferably flow outside the tube Flow outside the tube, when the flow is counter-current and inside the tube when the flow is co-current Flow at a very slow velocity ANSWER DOWNLOAD EXAMIANS APP
