Note: In the below video (Plot Pressure Contours), please note that the cursor disappears accidentally at the 44 second mark and returns at the 3 minute mark. At 1 minute 17 seconds, "here" refers to the bottom-middle of the region near the plate. It is later drawn at the 1 minute 28 second mark. At 2 minute 40 seconds, "here" refers to the left most face, known as the inlet face, of the region.

Drag
Now, we will obtain the drag on the plate. First, click on Report then click on Result Reports..., as shown in the following image.

In the case here, the density, viscosity and area all have values of 1. Thus, the equation above reduces to the following equation.
The results from ANSYS FLUENT agree with the theory here since the drag coefficient is approximately twice the value of the drag.
