The effective diffusion coefficient varied between 2.4 x10 <sup>-12 </sup> and 10.8 x10 <sup>-12 </sup> m <sup>2 </sup>s <sup>-1 </sup> for the entire range of experiments and increased with the pressure and flow rate. The model fitted well the experimental data (ADD varied between 2.35 and 7.48%). </p> <br />}, number={1}, publisher={Eskisehir Technical University}
