Mass Transfer If f = moles of vapour present per mole of feed, then the slope of feed line is - f/(1 - f) (1 - f)/f - (f - 1)/f - 1/f - f/(1 - f) (1 - f)/f - (f - 1)/f - 1/f ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Pick out the correct relationship. (where, Ri = internal reflux ratio Ro = external reflux ratio. ) (1 + Ri) = Ro/Ri (1 + Ro) = Ro/Ri (1 - Ro) = Ro/Ri (1 - Ri) = Ro/Ri (1 + Ri) = Ro/Ri (1 + Ro) = Ro/Ri (1 - Ro) = Ro/Ri (1 - Ri) = Ro/Ri ANSWER DOWNLOAD EXAMIANS APP
