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 Saturated steam is used for steam distillation Temperature is less Total pressure is less Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Saturated steam is used for steam distillation Temperature is less Total pressure is less ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer When the solvent dissolves very little of solute, then Very small quantity of solvent is required Solvent of low latent heat of vaporisation should be used Solvent of low freezing point should be used Large quantity of solvent is required to extract the solute Very small quantity of solvent is required Solvent of low latent heat of vaporisation should be used Solvent of low freezing point should be used Large quantity of solvent is required to extract the solute ANSWER DOWNLOAD EXAMIANS APP
