Assuming the validity of the De Priester (Dadyburjor) charts (K values), make the following VLE calculations for the methane(1)/ ethylene(2)/ ethane(3) system: a) BULB P, given x1=0.10,x2=0.50 and T=51C b) DEW P, given y1=0.50,y2=0.25 and T=51C c) BULB T, given x1=0.12,x2=0.40 and P=17.24 bar d) DEW T, given y1=0.43,y2=0.36 and P=17.24 bar
