Mass Transfer The diffusivity (D) in a binary gas mixture is related to the pressure (P) as D ∝ 1/P0.5 D ∝ 1/P D ∝ 1/P1.5 D ∝ P0.5 D ∝ 1/P0.5 D ∝ 1/P D ∝ 1/P1.5 D ∝ P0.5 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer During drying of a solid, the critical moisture content increases with Decreased drying rate Increased thickness of the solid Both B and C Increased drying rate Decreased drying rate Increased thickness of the solid Both B and C Increased drying rate 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 At some point of time, the operation is shifted to total reflux condition (i.e., no product and residue are being withdrawn and feed to the column is stopped).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, The top and bottom compositions correspond to the maximum enrichment available The top and bottom compositions are unchanged with and without total reflux 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 correspond to the maximum enrichment available The top and bottom compositions are unchanged with and without total reflux Reboiler load and condenser load are minimum Composition of vapors and that of liquid do not vary throughout the column ANSWER DOWNLOAD EXAMIANS APP
