Mass Transfer For gas absorption, low viscosity solvents are preferred, because of their Better flow characteristics All of these Rapid absorption rates Low pumping pressure drop Better flow characteristics All of these Rapid absorption rates Low pumping pressure drop ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer An air-water vapour mixture has a dry bulb temperature of 60°C and a dew point temperature of 40°C. The total pressure is 101.3 kPa and the vapour pressure of water at 40°C and 60°C are 7.30 kPa and 19.91 kPa respectively.The humidity of air sample expressed as kg of water vapour/kg of dry air is 0.122 0.048 0.079 0.152 0.122 0.048 0.079 0.152 ANSWER DOWNLOAD EXAMIANS APP

Mass Transfer In case of steam distillation, the steam leaving the liquid is not completely saturated with distillate vapour, because Temperature is less Total pressure is less Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Saturated steam is used for steam distillation Temperature is less Total pressure is less Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Saturated steam is used for steam distillation ANSWER DOWNLOAD EXAMIANS APP
