Mass Transfer Penetration theory states that the mass transfer co-coefficient is equal to (where, De is diffusivity and 't' is time) (De/t)1/2 (4De/t) (De.t)1/2 (4De/πt)1/2 (De/t)1/2 (4De/t) (De.t)1/2 (4De/πt)1/2 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 1 10 9 8 1 10 9 8 ANSWER DOWNLOAD EXAMIANS APP
