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) 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 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 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Solvent extraction is the terminology applied to the liquid-liquid extraction, which is preferred for the separation of the components of liquids, when One of the liquid components is heat sensitive Extracting solvent is cheaply & abundantly available One of the liquid components has very high affinity towards the solvent Viscosity of liquid components is very high One of the liquid components is heat sensitive Extracting solvent is cheaply & abundantly available One of the liquid components has very high affinity towards the solvent Viscosity of liquid components is very high ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer An air-water vapour mixture has a dry bulb temperature of 60°C and a dew point temperature of 40°C. The total pressure is 101.3 kPa and the vapour pressure of water at 40°C and 60°C are 7.30 kPa and 19.91 kPa respectively.The humidity of air sample expressed as kg of water vapour/kg of dry air is 0.152 0.079 0.122 0.048 0.152 0.079 0.122 0.048 ANSWER DOWNLOAD EXAMIANS APP
