Mass Transfer Reboiler is considered as one theoretical plate, because Reboiler itself contains one plate None of these Vapour is recycled to the column Of the assumption that vapour and liquid leaving the reboiler are in equilibrium Reboiler itself contains one plate None of these Vapour is recycled to the column Of the assumption that vapour and liquid leaving the reboiler are in equilibrium 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 Saturated steam is used for steam distillation Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Temperature is less Total pressure is less Saturated steam is used for steam distillation Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition ANSWER DOWNLOAD EXAMIANS APP
