Mass Transfer In case of absorption with exothermic reaction, for fluids having Pr = Sc; percentage change in heat and mass transfer flux will be the same for a given change in the degree of turbulence Pr = Sc = 1; total mass, momentum and thermal diffusivity will be the same Both A & B Pr = Sc ; there won Pr = Sc; percentage change in heat and mass transfer flux will be the same for a given change in the degree of turbulence Pr = Sc = 1; total mass, momentum and thermal diffusivity will be the same Both A & B Pr = Sc ; there won 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 At some point of time, the operation is shifted to total reflux condition (i.e., no product and residue are being withdrawn and feed to the column is stopped).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, Composition of vapors and that of liquid do not vary throughout the column The top and bottom compositions are unchanged with and without total reflux The top and bottom compositions correspond to the maximum enrichment available Reboiler load and condenser load are minimum Composition of vapors and that of liquid do not vary throughout the column The top and bottom compositions are unchanged with and without total reflux The top and bottom compositions correspond to the maximum enrichment available Reboiler load and condenser load are minimum ANSWER DOWNLOAD EXAMIANS APP
