Calculating for Two Points

To calculate the properties at two points, select the Two Points tab. The input property values at each point must be entered. The properties at both points are calculated. The results are displayed in the output section of the SteamCalc window. The name, value and unit for each property selected for display in the Output Control window is listed in the output display. In addition, the difference between the values at each point is displayed. Scroll bars are displayed if the output grid extends beyond the window area. 

When saturated liquid or vapor properties as selected as the second property value for the two point option, only Pressure or Temperature may be entered for the first property. Figure 7 shows an example of the input and output for a two point calculation.
