Mass Transfer The relation among various mass transfer co-efficients (M.T.C) for ideal gases is given by (where, Kc & Km are M.T.C. for equimolar counter diffusion with concentration & mole fraction respectively as the driving force. and, Kp = M.T.C. for diffusion of a gas through a stagnant inert gas with pressure as driving force.) None of these Kc = Kp/RT = Km . RT/P Kc = Kp . RT = Km . RT/p Kc = Kp = Km None of these Kc = Kp/RT = Km . RT/P Kc = Kp . RT = Km . RT/p Kc = Kp = Km 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 1 9 8 10 1 9 8 ANSWER DOWNLOAD EXAMIANS APP
