Mass Transfer If f = moles of vapour present per mole of feed, then the slope of feed line is - 1/f (1 - f)/f - (f - 1)/f - f/(1 - f) - 1/f (1 - f)/f - (f - 1)/f - f/(1 - f) ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer The diffusivity (D) in a binary gas mixture is related to the pressure (P) as D ∝ 1/P D ∝ 1/P1.5 D ∝ P0.5 D ∝ 1/P0.5 D ∝ 1/P D ∝ 1/P1.5 D ∝ P0.5 D ∝ 1/P0.5 ANSWER DOWNLOAD EXAMIANS APP
