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