Mass Transfer In continuous distillation, the internal reflux ratio (Ri) and the external reflux ratio (Re) are related as Ri = Re Ri = Re/(1 + Re) Ri = (1 - Re)/Re Ri = Re/(1 - Re) Ri = Re Ri = Re/(1 + Re) Ri = (1 - Re)/Re Ri = Re/(1 - Re) ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In case of steam distillation, the steam leaving the liquid is not completely saturated with distillate vapour, because 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 Temperature is less ANSWER DOWNLOAD EXAMIANS APP
