Mass Transfer A 25 cm x 25 cm x 1 cm flat sheet weighing 1.2 kg initially was dried from both sides under constant drying rate conditions. It took 1500 seconds for the weight of the sheet to reduce to 1.05 kg. Another 1m x 1m x 1cm flat sheet of the same material is to be dried from one side only.Under the same constant drying rate conditions, the time required for drying (in seconds) from its initial weight of 19.2 kg to 17.6 kg is 2000 1500 2500 1000 2000 1500 2500 1000 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
