For one of the binary systems listed in Table 13.10, based on Eq. (13.19) and the Wil- son equation, make the following calculations: (a) BUBLP: 1 = 60°C, x₁ = 0.3. (b) DEW P: 1= 60°C, y₁ = 0.3. (c) P,T-flash: t=60°C, P = (Pbubble + Pdew), Z₁ = 0.3. (d) If an azeotrope exists at t=60°C, find Paz and x²=yiz.
