Mass Transfer In a moderately sized packed absorption tower, channeling (which is most severe with stacked packings) can be minimised by taking the ratio of tower diameter to packing diameter > 8:1 > 4 :1 < 8 : 1 < 6:1 > 8:1 > 4 :1 < 8 : 1 < 6:1 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer 1 kg of a saturated aqueous solution of a highly soluble component A at 60°C is cooled to 25°C. The solubility limits of A are (0.6 kgA/kg water) at 60°C and (0.2 kgA/kg water) at 25°C. The amount in kg of the crystals formed is 0.2 0.25 0.4 0.175 0.2 0.25 0.4 0.175 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer To get high tray efficiency Interfacial surface between liquid and gas phase should be large Liquid entrainment should be severe Gas velocity should be very low Time of contact between the two phases should be less Interfacial surface between liquid and gas phase should be large Liquid entrainment should be severe Gas velocity should be very low Time of contact between the two phases should be less ANSWER DOWNLOAD EXAMIANS APP
