Heat Transfer in Fluids: Finding Average Temperature & Pressure vs. Time Graph

I'm just starting off with this Comsol business and loving it--Version 4.2. Unfortunately, I find myself working in a time crunch and helplessly inexperienced. Here is the problem:
I am modeling a long fuel pipe closed at both ends with an internal fuel pressure of 150 psi. The fuel is hotter than the ground and heat is transferring out of the fluid. I modeled the pipe as being two-dimensional with a set heat flux out of the fluid and initial temperatures of the fuel and the piping. As heat is transferred out of the pipe, the pressure in the tube decreases. The heat transfer creates rings of constant temperature with the center core close to the initial temperature and the outside ring a few degrees cooler. Simple enough.
My questions are...
1. How can I find the average temperature of the fuel in the pipe.
2. How can I graph a pressure v. time graph of the system.
You guys are awesome. Many thanks.
