Mass Transfer In case of steam distillation, the steam leaving the liquid is not completely saturated with distillate vapour, because 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 Temperature is less Total pressure is less Saturated steam is used for steam distillation ANSWER DOWNLOAD EXAMIANS APP
