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 ∝ P0.5 D ∝ 1/P1.5 D ∝ 1/P0.5 D ∝ 1/P D ∝ P0.5 D ∝ 1/P1.5 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer If a two phase system is in physical equilibrium; then it means that, the Total pressure throughout the liquid phase is equal to that throughout the vapor phase Escaping tendency of each component from the liquid phase to the vapor phase is exactly equal to that from vapor phase to liquid phase All of these Temperature of the liquid phase is equal to that of the vapor phase Total pressure throughout the liquid phase is equal to that throughout the vapor phase Escaping tendency of each component from the liquid phase to the vapor phase is exactly equal to that from vapor phase to liquid phase All of these Temperature of the liquid phase is equal to that of the vapor phase ANSWER DOWNLOAD EXAMIANS APP
