Mass Transfer In continuous distillation, the internal reflux ratio (Ri) and the external reflux ratio (Re) are related as Ri = Re/(1 + Re) Ri = Re/(1 - Re) Ri = (1 - Re)/Re Ri = Re Ri = Re/(1 + Re) Ri = Re/(1 - Re) Ri = (1 - Re)/Re Ri = Re 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 10⁻⁴ 8.5 x 10⁻³ 5.6 x 10⁻³ 8.5 x 10⁻⁴ 5.6 x 10⁻⁴ 8.5 x 10⁻³ 5.6 x 10⁻³ 8.5 x 10⁻⁴ ANSWER DOWNLOAD EXAMIANS APP
