Mass Transfer The feed to fractionating column is changed from saturated vapour to saturated liquid. If the separation and reflux ratio remains unchanged, the number of ideal stages will Depend on saturated boiling point; may increase or decrease Remains same Increase Decrease Depend on saturated boiling point; may increase or decrease Remains same Increase Decrease 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 = 1 S = ∞ S > 1 S < 1 S = 1 S = ∞ ANSWER DOWNLOAD EXAMIANS APP
