Problem 2. Tetrachloromethane at a concentration of 15mg/L(Cw) is to be reduced to 15g/L (Cw) by an air stripping tower. What is the required height (L) and the concentration of tetrachloromethane at the exit air (Ca) for the following conditions: (25p) Air to water flow ratio (Q2/Qw)=40:1 Qw=25m3/h Cylindrical tower diameter (d)=1m Henry's constant (H) for tetrachloromethane =0.98Lw/L Water diffusion coefficient for chloroform (Dw)=3109m2/s Water kinematic viscosity (vw)=8.9107m2/s Problem 2.
