Mass Transfer A distillation column with N plates is being operated under normal conditions. At some point of time, the operation is shifted to total reflux condition (i.e., no product and residue are being withdrawn and feed to the column is stopped). At the new steady state, Composition of vapors and that of liquid do not vary throughout the column The top and bottom compositions correspond to the maximum enrichment available Reboiler load and condenser load are minimum The top and bottom compositions are unchanged with and without total reflux Composition of vapors and that of liquid do not vary throughout the column The top and bottom compositions correspond to the maximum enrichment available Reboiler load and condenser load are minimum The top and bottom compositions are unchanged with and without total reflux ANSWER DOWNLOAD EXAMIANS APP

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 1000 2500 1500 2000 1000 2500 1500 2000 ANSWER DOWNLOAD EXAMIANS APP
