PV Elite populates the height and other dimensions for your vessel with sample data, which you can alter to your vessel specifics. PV Elite made certain assumptions as you built the model, including diameter, thicknesses, lengths, and materials.
-
Before we look at the dimensions, select the bottom head in either the 2D or 3D model. This will select the bottom head as the current component.
If you look at the 2D model, you will see that the bottom head is a lighter color.
-
Let us look at the dimensions PV Elite chose for the current component (the lighter color in the illustration above). The details will look like this:
Here are the major assumptions for this example:
Inside Diameter: 96 inches
Straight Flange: 0.1667 feet (which is 2 inches)
Finished Thickness: 0.25 inches
Internal Corrosion: 0.125 inches
External Corrosion: 0
Internal Pressure: 100 psi
External Pressure: 15 psi
Temperatures: 100 °F
Head Aspect Ratio: 2 (Head Factor)
There is other information, but let us make some changes to suit our vessel. First we change the dimensions and the pressure:
New Values:
Inside Diameter: 60 inches
Finished Thickness: 0.5 inches
Internal Corrosion: 0.0625 inches
External Corrosion: 0.0625 inches
Internal Pressure: 120 psi
Temperatures: 200 °F
Your screen might look different, but follow along, and it will become clear. If
you are accustomed to working in the metric system, we shall address that situation
shortly.

Now, enter the new diameter by typing 60:

Next, press the Enter key on your keyboard twice to move the cursor down to the next field:

If you do not want to change the straight flange, press Enter again, and it will move to the next field. You should be able to complete the entries for your new dimensions:
