Solute A is absorbed from an inert gas into liquid B in a 0.5-m- long wetted wall column. The initial concentration of A in the liquid is 2 kgmol/m and the partial pressure of A in the gas is 0.015 atm. The concentration of A in the gas and liquid at the interface are related by the expression: CA = 150PA Where: PA has unit of atm and CA has unit kgmol/m. If the maximum velocity of liquid is 0.03 m/sec. Determine the following: a) The concentration of A at point 0.01 m from the gas-liquid interface. b) The penetration distance of A in the liquid. m2 Assume that the diffusion coefficients constant and has value of 9.0x 10-8, sec
