Mass Transfer Inside the distillation column, the None of these Liquids are not always at their bubble points Driving force for the vapour flow is the pressure drop Pressure increases gradually from bottom to the top of the column None of these Liquids are not always at their bubble points Driving force for the vapour flow is the pressure drop Pressure increases gradually from bottom to the top of the column 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 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 Total pressure is less Temperature 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 Total pressure is less ANSWER DOWNLOAD EXAMIANS APP
