Mass Transfer The term "cooling range" in a cooling tower refers to the difference in the temperature of Hot water entering the tower and the wet bulb temperature of the surrounding air Hot water entering the tower and the cooled water leaving the tower None of the listed here Cold water leaving the tower and the wet bulb temperature of the surrounding air Hot water entering the tower and the wet bulb temperature of the surrounding air Hot water entering the tower and the cooled water leaving the tower None of the listed here Cold water leaving the tower and the wet bulb temperature of the surrounding air ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer An aqueous solution of methanol is to be distilled in a tray column. High pressure steam is available as a source of heat. For a given reflux ratio and overhead composition, two options are being explored; (i) a reboiler is used and (ii) no reboiler is used but steam is fed directly to the bottom of the column. As compared to option (i), in option (ii) Composition of the residue remains unchanged Less number of trays are required More number of trays are required and the residue composition is more dilute in methanol More number of trays are required but the residue composition remains unchanged Composition of the residue remains unchanged Less number of trays are required More number of trays are required and the residue composition is more dilute in methanol More number of trays are required but the residue composition remains unchanged 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 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 5.6 x 10⁻³ ANSWER DOWNLOAD EXAMIANS APP
