Our next challenge is to produce velocity vectors. This is a very similar process to creating the temperature contours above. On the top menu, click on vector . Please name it "Velocity Vector" and click OK. Under Details of Velocity Vector, select periodic 1 for Locations. Select Velocity for Variable. This tells CFD-post we are looking for vector plots of velocity.

In the next step, we will specify the appearance of vector arrows. Select the Symbol tab. Enter 0.05 for Symbol Size. This again is dependent on personal preference.

...

You will see Details of Wall Temperature appear on the lower left panel. Under General tab, please name the chart "Wall Temperature".

Now click on Data Series tab to specify the location of the chart data. Create a new data series .  Change the name from Series 1 to FLUENT. Under Data Source, specify Wall as Location.

...

Next, we will create a chart using this Location data. 
Insert > Chart 
Enter "Axial Pressure" as Name. You will see Details of Axial Pressure appear on the lower left panel. Under General, name the chart "Pressure Variation along Pipe Axis".

Now click on Data Series tap to specify the location of the chart data. Create a new data series .  Change the name from Series 1 to FLUENT. Under Data Source, specify Centerline as Location. The centerline was already created while doing the temperature variation along the center-line. If that chart was skipped please refer to that section on how to create a centerline.
We would also like to compare our simulation result with experimental data. Experimental data is can be downloaded here. Download it to the directory that you like. Now, click a new data series . Name it Experiment. Under Data Source, select File and browse for the downloaded experimental data.

Our purpose in this exercise is to study the pressure variation along the length of the pipe. Therefore our chart should show pressure in the y-axis and x-position in the x-axis.

Continue the same step for creating line Outlet (x=6.096m)

Check that you have the following under Outline.

Now we will have enough interval to look at the flow development before and after the heating.  Let's create a chart to investigate this.
