• the temperature increases in the heated section
• the temperature is much higher near the wall in the heated section
• the temperature is nearly uniform at the end of the mixing section
  All these trends are as expected.

and Wall Temperatures

The following video shows videos show you the procedure for calculating the mixed mean temperature and wall temperatures at x=2.67 m. To repeat the calculation at a different axial location, you can right-click on appropriate items in the tree, duplicate and modify as necessary. You need to double-click on an item in the tree to modify it; this is easy to overlook.
