A flash unit is used to separate any mixture into liquid and vapour streams at equilibrium. The compositions of the streams depend on the quantity of the feed vaporized. If the vapour-liquid equilibrium relationship is expressed in terms of equilibrium constants; calculate =V/F ratio using the Bisection Method (=0.03). The following data and equation are given as; f()=i=1n(Ki1)+1Zi1=00.1
