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