Mass Transfer Plate towers are preferred to packed towers, when large temperature changes are involved, because of the reason that the Viscosity variation of the fluids may cause channeling/flooding Packing may be crushed due to thermal expansion/contraction of the components of the equipments None of these Pressure drop in the equipment will be very high Viscosity variation of the fluids may cause channeling/flooding Packing may be crushed due to thermal expansion/contraction of the components of the equipments None of these Pressure drop in the equipment will be very high ANSWER DOWNLOAD EXAMIANS APP

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 10⁻³ 8.5 x 10⁻⁴ 5.6 x 10⁻⁴ 5.6 x 10⁻³ 8.5 x 10⁻³ 8.5 x 10⁻⁴ 5.6 x 10⁻⁴ ANSWER DOWNLOAD EXAMIANS APP
