Mass Transfer Plate towers are preferred to packed towers, when large temperature changes are involved, because of the reason that the None of these Viscosity variation of the fluids may cause channeling/flooding Pressure drop in the equipment will be very high Packing may be crushed due to thermal expansion/contraction of the components of the equipments None of these Viscosity variation of the fluids may cause channeling/flooding Pressure drop in the equipment will be very high Packing may be crushed due to thermal expansion/contraction of the components of the equipments ANSWER DOWNLOAD EXAMIANS APP
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 At some point of time, the operation is shifted to total reflux condition (i.e., no product and residue are being withdrawn and feed to the column is stopped).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, 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 Composition of vapors and that of liquid do not vary throughout the column The top and bottom compositions correspond to the maximum enrichment available ANSWER DOWNLOAD EXAMIANS APP
