Heat transfer along a pipe - excel calcs?
Posted 01 August 2011 - 01:42 PM
What I'm looking for is an excel file or any guidance to help me calculate the approximate temperature drop along a given length length of pipe. We often wrap pipe spools for heat treatment, and frequently have sensitive equipment/valves in proximity to the heater pads/insulation. I'm looking for something that will allow me to ballpark "in still air with no air/fluid flow through the pipe ID, a pipe of X thickness will see a temperature drop of approximately Y degrees over Z inches from the heat source."
Any help would be greatly appreciated.

As far as knowing it... pfft. Been a long time since I've dealt with anything not specific to metallurgy or welding codes.

"We often wrap pipe spools for heat treatment..." what is the wrap?
"in still air with no air/fluid flow through the pipe ID..." You're still going to have natural convection.
I think I can help with setting up a spreadsheet for playing with the variables, but a generic sketch of a setup would be nice.
