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.) Kc = Kp = Km 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 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer H₂S is being absorbed in a gas absorber unit. The height of the transfer unit based on the overall mass transfer coefficient on the gas side is 0.4 m. The equilibrium data is given by, y = 1.5 x. The bulk concentration of H₂S has to be reduced from 0.05 to 0.001 mole fraction in the gas side. The height of the tower (in metres) corresponding to an operating line given by, y = 5x + 0.001 is 1 1.56 0.56 2 1 1.56 0.56 2 ANSWER DOWNLOAD EXAMIANS APP
