Mass Transfer To get high tray efficiency Gas velocity should be very low Time of contact between the two phases should be less Liquid entrainment should be severe Interfacial surface between liquid and gas phase should be large Gas velocity should be very low Time of contact between the two phases should be less Liquid entrainment should be severe Interfacial surface between liquid and gas phase should be large 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 vapor phase follows Raoult's law Vapor phase obeys Dalton's law and liquid phase obeys Raoult's law Only liquid phase obeys Dalton's law Liquid phase obeys Dalton's law and vapor phase obeys Raoult's law Only vapor phase follows Raoult's law Vapor phase obeys Dalton's law and liquid phase obeys Raoult's law Only liquid phase obeys Dalton's law Liquid phase obeys Dalton's law and vapor phase obeys Raoult's law ANSWER DOWNLOAD EXAMIANS APP
