Chapter 04.06 Gaussian Elimination – More Examples Chemical Engineering Example 1 A liquid-liquid extraction process conducted in the Electrochemical Materials Laboratory involved the extraction of nickel from the aqueous phase into an organic phase. A typical set of experimental data from the laboratory is given below. Ni aqueous phase, ( 29 l g a 2 2.5 3 Ni organic phase, ( 29 l g g 8.57 10 12 Assuming g is the amount of Ni in the organic phase and a is the amount of Ni in the aqueous phase, the quadratic interpolant that estimates g is given by 3 2 , 3 2 2 1 + + = a x a x a x g The solution for the unknowns 1 x , 2 x , and 3 x is given by = 12 10 57 . 8 1 3 9 1 5 . 2 25 . 6 1 2 4 3 2 1 x x x Find the values of 1 x , 2 x , and 3 x using naïve Gauss elimination.
