A seven-component mixture is flashed at a specified temperature and pressure.(a) Using the K-values and feed composition given below, make a plot of the Rachford-Rice flash function at intervals of ? of 0.1, and from the plot estimate the correct root of ?.(b) An alternative form of the flash function is Make a plot of this equation also at intervals of ? of 0.1 and explain why the Rachford-Rice function is preferred. z:(1 - K;) I+ V(K - 1) f{W) = 2 z K;

z:(1 - K;) I+ V(K - 1) f{W) = 2 z K; fIV) = E 1+ V(K; 1) K, Component 0.0079 16.2 1 0.1321 5.2 0.0849 2.6 0.2690 1.98 0.0589 0.91 0.1321 0.72 0.3151 0.28 -23 4n 67
