### 7.2.2. Graphics Display

The graphics display contains two tabs that display the following after a design has been calculated:

- Sketches
- Efficiency Chart

#### 7.2.2.1. Sketches

- Impeller

  After you click Calculate, you can view the meridional sketch of the impeller in the graphics display as shown in Figure 7.2: Example Meridional Sketch of the Impeller. To view this sketch, ensure that `Impeller` is selected in the component selection control, and click the Sketch tab.

- Volute

  After you click Calculate, you can view the central section sketch of the volute in the graphics display as shown in Figure 7.3: Example Central Section Sketch of the Volute Geometry. To view this sketch, ensure that `Volute` is selected in the component selection control, and click the Sketch tab.

#### 7.2.2.2. Efficiency Chart

After you click Calculate, the pump efficiency chart is shown in the Graphics Display under the `Efficiency Chart` tab. The plot shows the overall pump efficiency against the non-dimensional specific speed for flow rate to speed ratios (Q/N) ranging between 0.0001 and 1.0. The current design is indicated on the plot by a black square.

Note that if imperial units are used then , the specific speed measure commonly used in the United States, is used in place of . An example efficiency chart is shown in Figure 7.4: Overall Pump Efficiency Chart.
