Process Equipment and Plant Design In a shell and tube heat exchanger, the overall heat transfer co-efficient is proportional to the tube side (volumetric flow rate)0.8. This is valid, only when the ratio of the tube side film resistance to the total resistance is almost equal to 1 2 ∞ 20.8 1 2 ∞ 20.8 ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In actual operation of distillation column, the vapour is not distributed uniformly among the bubble caps, primarily because of the Lower static submergence Small downcomer liquid seal Liquid gradient on the tray Lower skirt clearance Lower static submergence Small downcomer liquid seal Liquid gradient on the tray Lower skirt clearance ANSWER DOWNLOAD EXAMIANS APP
