Process Equipment and Plant Design When one of the fluids is highly corrosive and has fouling tendency, it should 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 Flow at a very slow velocity Preferably flow inside the tube for its easier internal cleaning 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 Flow at a very slow velocity Preferably flow inside the tube for its easier internal cleaning 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 Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Results in higher shell side pressure drop 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 Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Results in higher shell side pressure drop Can accomodate less number of tubes for a given shell diameter ANSWER DOWNLOAD EXAMIANS APP
