Now that we have our data sources, we will proceed by specifying the axes. Starting with the We want to see the variation of temperature with the length of the pipe. Therefore, temperature will be on the y axis of the chart and x-position on the x axis of the chart. We will start by defining the X-axis: 

Click on X Axis tab. Next to Variable, choose X.

Now we will specify the Y Axis parameter. the y axis: Click on Y Axis tab. Next to Variable, choose Temperature.

Now we will specify how that the chart specifications are defined, we want to customize the chart to display. The default setting is to display the all data series in lines. Since using line charts, but since we only have 3 very few experimental points, we want them to be displayed in data points. it would be more logical to display the experimental data using data points: Click on Line Display. Then click on experimental tab tab.  Select "Experimental" . Next to Line Style, change Automatic to None. Next to Symbols, change None to Diamond. Change the color to red. Click Apply. You will We have are now displaying experimental data using data points denoted by red diamonds.

From this it is obvious the experimental data compares quite well to simulation results. This would be more accurate if we had more experimental data points to work with, but as it is not the case, we can only assume that the in between stages match just as well as the inlet and outlet temperatures.

Wall Temperature Plot

We will now investigate the temperature variation along the wall. To do this we need to create a new line on the simulation. It needs to be a horizontal line very close to the wall

Pressure Plot

Now let's us look at the pressure variation at the centerline. First, we will create a line call centerline.

Insert > Location > Line

Name it "CenterlineWall" and click OK. On the lower left panel, you will see Details of CenterlineWall. Enter the following coordinates.

Point 1 (0,0.0294,0)

Point 2 (6.096,0.0294,0)

Enter 50 for Samples. (This will be is the number of sample points used when plotting data)

Click Apply.

You will see centerline wall created under User Locations and Plots.
Next, we will create a chart repeat the previous process, but using this Location new line as source data. 
Insert > Chart Chart

Enter "Axial Pressure" as Name. You will see Details of Axial PressureWall Temperature appear on the lower left panel. Under General tab, give please name the chart Title as "Pressure Variation along Pipe Axis"Wall Temperature".

Now click on Data Series tap 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 Centerline Wall as Location.

Now, click a new data series . Name it Experiment. Under Data Source, select File and browse to for the downloaded experimental data.

Axial Velocity Profile

Now let's us look at the axial velocity profile at various location in the pipe. We are interested in the flow development before the heated section and would like to observe how heat addition in the heated section will affect the flow development. To do this, let's start with investigation the flow before the heated section.
