Mass Transfer In a moderately sized packed absorption tower, channeling (which is most severe with stacked packings) can be minimised by taking the ratio of tower diameter to packing diameter > 4 :1 < 6:1 < 8 : 1 > 8:1 > 4 :1 < 6:1 < 8 : 1 > 8:1 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 8.5 x 10⁻³ 8.5 x 10⁻⁴ 5.6 x 10⁻³ 5.6 x 10⁻⁴ 8.5 x 10⁻³ 8.5 x 10⁻⁴ 5.6 x 10⁻³ 5.6 x 10⁻⁴ ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In an operating distillation column, the Vapors and liquids are at their dew point and bubble point respectively Driving force for the vapor flow is the pressure drop, as the pressure decreases gradually from the bottom to the top of the column Highest temperature is encountered at the top of the column Driving force for the liquid flow is its specific weight Vapors and liquids are at their dew point and bubble point respectively Driving force for the vapor flow is the pressure drop, as the pressure decreases gradually from the bottom to the top of the column Highest temperature is encountered at the top of the column Driving force for the liquid flow is its specific weight ANSWER DOWNLOAD EXAMIANS APP
