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 Acetone is to be removed from air in an isothermal dilute absorber using pure water as solvent. The incoming air contains 5 mole% of acetone (yin = 0.05). The design equation to be used for obtaining the number of trays (N) of the absorber is, N+2 = 6 log (yin/yout).For 98% recovery of acetone, the number of trays required is/are 10 8 9 1 10 8 9 1 ANSWER DOWNLOAD EXAMIANS APP
