Mass Transfer Experiments were conducted to determine the flux of a species A in a stagnant medium across a gas-liquid interface. The overall mass transfer co-efficient based on the liquid side for dilute systems for the above was estimated to be 4 x 10⁻³ kg mole/m².s. The equilibrium data for the system is given as y = 2x. The flux across the interface (in kg mole/m² .s) for bulk concentrations of A in gas phase and liquid phase as y = 0.4 and x = 0.01 respectively is 5.6 x 10⁻³ 8.5 x 10⁻⁴ 8.5 x 10⁻³ 5.6 x 10⁻⁴ 5.6 x 10⁻³ 8.5 x 10⁻⁴ 8.5 x 10⁻³ 5.6 x 10⁻⁴ 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 Only liquid phase obeys Dalton'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 vapor phase follows Raoult's law Only liquid phase obeys Dalton'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 ANSWER DOWNLOAD EXAMIANS APP
