Mass Transfer As the reflux ratio in a distillation coloumn is increased from the minimum, the Total cost first decreases and then increases Liquid flow increases while the vapor flow decreases for a system Slope of the operating line in stripping section decreases Number of plates decreases very slowly first and then more and more rapidly Total cost first decreases and then increases Liquid flow increases while the vapor flow decreases for a system Slope of the operating line in stripping section decreases Number of plates decreases very slowly first and then more and more rapidly ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In gas-liquid contact operation, the number of ideal stages, N = (xa - xb)/(xb - x*b) . This is true when the stripping factor 'S' is S = 1 S > 1 S = ∞ S < 1 S = 1 S > 1 S = ∞ S < 1 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 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 ANSWER DOWNLOAD EXAMIANS APP
