Mass Transfer If f = moles of vapour present per mole of feed, then the slope of feed line is - 1/f - f/(1 - f) (1 - f)/f - (f - 1)/f - 1/f - f/(1 - f) (1 - f)/f - (f - 1)/f ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Absorption factor is defined as (where, S₁ = slope of the operating line S₂ = slope of the equilibrium curve) S₁ - S₂ S₂/S₁ S₁ x S₂ S₁/S₂ S₁ - S₂ S₂/S₁ S₁ x S₂ S₁/S₂ ANSWER DOWNLOAD EXAMIANS APP
