Analysis of Liquid and Vapor Phase Compositions and Flow Rates in a Multicomponent System: A MATLAB Simulation Matlab code function project1(z,k,k_end,F,xLeft,xRight) % This program plot the output compositions and flow rates in both phases as % functions of K7 as K7 varying from 0.05 to 4.00 by taking n - component system % with the feed compositions , K - values, total feed rate, bracket interval % for roots and the range of k7( or nth k ) % Input:: % z values % k values % k_end in the form [a b] ; in this case its k7 [0.05 4] % F -- feed rate % xLeft : Initial Lower Guess % xRight : Initial Upper Guess % Output:: % Plot the output compositions and flow rates in both phases as % functions of K7 as K7 varies from 0.05 to 4.00. % Sample Test: % F = 1500; % z = [0.16,0.09,0.21,0.13,0.06,0.15,0.20]; % k = [3.52,1.92,1.22,0.84,0.43,0.08]; % k7 = 0.05:0.01:4; % xLeft = 0; % xRight = 1; % k_end = [0.05 4]; % project1(z,k,k_end,F,xLeft,xRight) % generating values of k7 in the given interval k7 = k_end(1):0.01:k_end(2); % check for no of inputs if nargin<6,error( 'minimum 6 input arguments required' ), end % declare the output variables root = zeros(1,length(k7)); V = zeros(1,length(k7)); L = zeros(1,length(k7)); x = zeros(length(k7),length(z)); y = zeros(length(k7),length(z)); for i=1:length(k7) k1 = [k,k7(i)]; root(i) = BracketBisect(z,k1,xLeft,xRight); V(i) = root(i)*F; L(i)=F - V(i); for j=1:length(z)
