among those points are points corresponding to T=400F and p=500lbf/in2. Learn how to connect the points by solid lines in Excel, but make sure the points are still visible. Example: 2. Add to the p-v diagram a function T(v)=400F that includes 3 branches: one in the liquid phase (Table A-5E), one in the two-phase mixture (inside the vapor dome, Table 2E ), and one in the vapor phase (Table A-4E). Make sure that the data points are visible and connected by a solid line. It is enough to use 2 points per branch in the liquid and liquid-vapor mixture phases, and 3- 4 points in the vapor phase. 3. Add to the T-v diagram a function p(v)=500lbf/in2 that includes 3 branches: one in the liquid phase (Table A-5E), one in the two-phase mixture (inside the vapor dome, Table 3E ), and one in the vapor phase (Table A-4E). Make sure that the data points are visible and connected by a solid line. It is enough to use 2 points per branch in the liquid and liquid-vapor mixture phases, and 3-4 points in the vapor phase. Notice that lines of constant T and p may grow very rapidly in the liquid phase. To improve the plot quality in the liquid phase, apply the log scale to both axes..
