Mass Transfer 1 kg of a saturated aqueous solution of a highly soluble component A at 60°C is cooled to 25°C. The solubility limits of A are (0.6 kgA/kg water) at 60°C and (0.2 kgA/kg water) at 25°C. The amount in kg of the crystals formed is 0.4 0.175 0.25 0.2 0.4 0.175 0.25 0.2 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 10⁻⁴ 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 8.5 x 10⁻³ ANSWER DOWNLOAD EXAMIANS APP
