Mass Transfer A distillation column with N plates is being operated under normal conditions. At some point of time, the operation is shifted to total reflux condition (i.e., no product and residue are being withdrawn and feed to the column is stopped). At the new steady state, Composition of vapors and that of liquid do not vary throughout the column The top and bottom compositions are unchanged with and without total reflux Reboiler load and condenser load are minimum The top and bottom compositions correspond to the maximum enrichment available Composition of vapors and that of liquid do not vary throughout the column The top and bottom compositions are unchanged with and without total reflux Reboiler load and condenser load are minimum The top and bottom compositions correspond to the maximum enrichment available ANSWER DOWNLOAD EXAMIANS APP

Mass Transfer The reason for preferring packed towers over plate towers in distillation practice is that the packed tower operation gives Low pressure drop and high hold up High pressure drop and low hold up High pressure drop and high hold up Low pressure drop and low hold up Low pressure drop and high hold up High pressure drop and low hold up High pressure drop and high hold up Low pressure drop and low hold up ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Relative volatility varies with the concentration of component for an ideal solution. The relative volatity of a binary mixture may be defined as the ratio of vapor pressure of component 'A' to that of component 'B', when Only liquid phase obeys Dalton's law Liquid phase obeys Dalton's law and vapor phase obeys Raoult's law Vapor phase obeys Dalton's law and liquid phase obeys Raoult's law Only vapor phase follows Raoult's law Only liquid phase obeys Dalton's law Liquid phase obeys Dalton's law and vapor phase obeys Raoult's law Vapor phase obeys Dalton's law and liquid phase obeys Raoult's law Only vapor phase follows Raoult's law ANSWER DOWNLOAD EXAMIANS APP
