Process Equipment and Plant Design When one of the fluids is highly corrosive and has fouling tendency, it should Flow at a very slow velocity 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 Preferably flow inside the tube for its easier internal cleaning Flow at a very slow velocity 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 Preferably flow inside the tube for its easier internal cleaning ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Mc Cable Thiele method used for finding theoretical stages in a distillation column assumes that the All of these Trouton's rule is applicable Sensible heat differences are small, because the temperature changes from tray to tray is small Liquid/vapor loading across the column remains constant All of these Trouton's rule is applicable Sensible heat differences are small, because the temperature changes from tray to tray is small Liquid/vapor loading across the column remains constant ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design A perforated plate has holes of diameter dh arranged in a pitch ph. Each hole has a tube of I.D. dt passing through it. The ligament efficiency is given by (ph - dh)/ph (ph - dt)/ph (ph - dh)/dh (ph - dh . dt/2)/ph (ph - dh)/ph (ph - dt)/ph (ph - dh)/dh (ph - dh . dt/2)/ph ANSWER DOWNLOAD EXAMIANS APP
