Mass Transfer Pick out the correct relationship. (where, Ri = internal reflux ratio Ro = external reflux ratio. ) (1 - Ri) = Ro/Ri (1 + Ro) = Ro/Ri (1 - Ro) = Ro/Ri (1 + Ri) = Ro/Ri (1 - Ri) = Ro/Ri (1 + Ro) = Ro/Ri (1 - Ro) = Ro/Ri (1 + Ri) = Ro/Ri ANSWER DOWNLOAD EXAMIANS APP

Mass Transfer In a distillation column, with increase in the reflux ratio, the heat removed in the cooler And the heat required in reboiler decreases Decreases Remains unaffected Increases And the heat required in reboiler decreases Decreases Remains unaffected Increases ANSWER DOWNLOAD EXAMIANS APP
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 Total pressure is less Temperature 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 Total pressure is less Temperature is less Saturated steam is used for steam distillation ANSWER DOWNLOAD EXAMIANS APP
